37 2011-09-12 03:30 Tonight's commute

i've been biking to work even more often. it's not a bad commute: only four miles one way (though there are some hills that are a lot more significant than flat miles). usually i take either the most direct way (all on roads, including busy 5 lane road) or a route that makes use of fayetteville's bike trails (then i just have to cross the busy road).

probably the main reason (psychologically) i like to bike is that it's more interesting/adventurous. (there are logical reasons too: exercise is healthy, saving a bit of gasoline, being a bit green. by the way i work for a green bio-energy company, so saving gas feels in the right spirit.) it feels more like i've accomplished something by getting to my destination. these are basically the same reasons i used to ride an 80cc honda before it broke and i took it apart without fixing it...)

i got a mountain bike last winter, and it's what i've been commuting on. it's not particularly well suited to paved roads, so i've been shopping for a dedicated commuting bike. but this reminded me that i haven't actually been mountain biking a lot lately. i think it's fair to blame this mostly on the super hot summer we had. i biked early in the morning a couple times during the summer, pulling my 3-year-old with her bike attached to mine. the last time went off-road was july 9.

anyway, the nice weather is here now, so i thought it was time for some mountain biking. so when i left work at 12:30am, i headed in a different direction. after one large hill i stopped at a walmart neighborhood market for some AAA batteries, as my helmet headlight was getting a bit dim. (it was my first ever time in this store, as i've boycotted it on principle ever since it was put in right across the street from another fairly new grocery store.) i walked right in with my bike, since i don't take a lock to work, and i seemed to be the only customer. one checkout was open but i had to find the cashier nearby.

then it was on to lake fayetteville under a full moon. i encountered maybe three dozen very surprised deer while on the paved part of the trail, followed by varied other fauna. then i turned on my headlight and veered into the woods. at the bottom of the first hill i stopped short twenty feet from a skunk. he did begin to retreat, but he was staying on the trail, and of course going much slower than i wanted to. after a minute or so of shining my light at him and ringing my pedestrian-alerting bell, he finally moved off the trail. in fact, he was out of sight, and i couldn't tell exactly where he was, though i was pretty sure he was still within eight feet of the trail. i took my chance and zipped past before he could do anything about it. it worked out ok.

after this, and maybe worst of all, were a series of big spider webs (and occupants) that i could see a fraction of a second in advance, just enough time to mostly duck under most of most of them. i say worst because ducking your head that fast (keep in mind i'm wearing a bike helmet with an LED headlamp strapped to it) is rough on the neck. actually, the downward motion is fine; it's the stopping of the downward motion that's rough. i may feel that tomorrow.

(i'm sure this little jaunt was nothing compared to k-ro's many muddy cambodian nightime rides.)

anyway, then it was on to another walmart for some groceries. again, no lock, and by now it's 1:30am, so i again propped my bike just inside the door (which is by the produce, which was what i wanted), but this is not just a neighborhood market, there are actually some customers and quite a few employees in sight one of whom informs me that i can't leave my bike there. i say, ok, i won't, and wheel it on into the store with me. they didn't have a single piece of organic fruit. but i grab a few things, and since my bike is safely with me i feel ok going all the way to the peanut butter aisle near the back. i check out and still get home at the same time that i did after having to stay late at work yesterday.

reminds me of a midnight ride or two (and numerous runs) that phil swope and i went on in college. on one, i hit an unseen hole in the road at high speed, had to bail off the seat, and, still holding the handlebars, skated down the road on the metal cleats attached to my bike shoes, no harm done. maybe i was little lucky there. but a couple more miles out, near the city limits, my free wheel broke, and i had too push the bike back to the dorm like a scooter.

also reminiscent of when i road to west fork at night on the not-yet-paved I-540. with no light that time. and a light-less, moon-less hike a couple miles through the woods as part of a "bachelor party". and a lightless cave exit (best way to avoid both falling and head-bumping is to crawl backwards). interestingly memorable, this category of activities.

16 2004-12-25 22:55 cave cont'd

i actually have a couple other somewhat freaky stories from that cave that i didn't even include. well, one isn't really a story, 'cause it happened really fast (at least, the exciting part did).

it was when carl and ian and i did the route, the first time. at the "wetter crawl" place you can optionally go up and over. so i went first and did that, but it was a tough climb down. i got part-way down and then i was just slipping and knew i couldn't hold on. so i jumped, without seeing in advance where i was going to land. i mean, i had already seen how far down it was and roughly the shape, but i wasn't looking (or at least, my light wasn't yet pointed there) when or just before i jumped. and the shape was not a flat, dry floor, it was a round, sloping wet floor. anyway, i sort of knew what direction had looked the flatest, and on the way down i pointed my light and i managed to land without slipping and not damage myself. but i strongly encouraged ian and carl to take the wet way instead. they begrudged me my dryness a bit, but were persuaded to take the safer way.

i have since learned that headlamps are a good way to see without having to hold and point a flashlight.

the other story happened was before i had done the birth canal, the night phil and i were in the cave after dark and had half-eaten acorns thrown at us from the trees (presumably by annoyed squirrels) when we went back out to the truck to get my few scraps of rope, which i then proceeded to patch together and use to lower myself down at the rappelling place. i got to where the wall had fallen away from me, hanging free, but from there i decided the rope wasn't long enough. but although descending was easy, going back up was not, and i was quickly tiring just maintaining altitude. but i didn't know where i would be if i dropped. (plus it was a pretty long drop, though it looked doable, maybe. plus there was a coleman lantern hanging from me.) so i decided i'd better do something quick. the rope was too small to grip (i had fashioned myself a seat-harness and as i recall was lowering myself pulley-style with a mechanical advantage of two, plus friction) so i just started wrapping it around my wrist to ascend. when i put my feet on the wall above/in front of me it caused my back pocket to empty itself of my mag-lite. and after i unwound the rope from my hand at the top, my hand was tingly for a week.

yeah, it was a bit harder to climb that rope than i had thought. and yes, it was a kind of dumb stunt and i'm lucky i didn't get hurt. keep in mind though that it wasn't really very far down. (and i must say i think i could have caught the rope and climbed back up if i had to. it actually would have been easy to reach if not from directly below then at least by jumping from the uphill side of the floor. i just didn't want to have to do that.) i would have felt better about the option of dropping down there if i had known the birth canal route. or--if i had still climbed back--at least i would have known how to retrieve my flashlight, if i thought it was worth an hour or two more and a lot of crawling. (one more narrative note: later that same night we built raccoon booby traps at our campsite.)

the lesson learned: from the fact that you can climb a thick rope without difficulty it doesn't necessarily follow that it'll be easy to climb a thin rope.

anyway, both of those were "hmm, maybe now i should start worrying just a bit" moments. more worrying in fact than the cave-in, if not quite as freaky.

14 2004-12-23 15:17 cave craziness

here's what i did last weekend. actually last summer, but it was interesting to me, being one of the more freaky things i've ever experienced. i blog it now because i just ran across the sheet of paper on which i documented it.

first, about bat cave. it's a public access cave in the buffalo national river wilderness management area (national park service), near boxley arkansas (which is a few miles upstream from ponca, the first common starting point for floats). the cave is open from may 15 to august 15 every year. the rest of the time it is closed (by a fence around the entrance) to protect the somewhat endangered grey bats that live there.

as a child, through high school, i would spend a week or two at ponca bible camp each summer. every afternoon we'd swim in the river. on wednesday we'd hike the lost valley (state park between ponca and boxley) trail and picnic. on thursday we'd go to bat cave.

we'd walk in through the large main passage--with very minor clambering in a couple spots but high ceilings everywhere--to the large chamber notable for a little dry (whenever we were there) stream bed running through the middle, and a manmade hole in the the floor about the size and depth of an open grave. after a few minutes of the kids exploring the slopes around the walls, we'd all turn off our flashlights and sing some worship songs before heading back out.

one summer i gained a bit of notoriety for "discovering" (certainly it had been discovered by many before, but none from our group) a tunnel that went up and over the ceiling of the room and opened up at a place above the far wall that would have been very difficult (and dangerous) to climb up to. thus some people, not knowing about the tunnel, were surprised to see me up there.

one year when i was old enough to go to high school week (1990 or thereabouts), somebody decided to take us through the birth canal. off the main passage into the large room there's a side passage, with a steep slope down to the entrance of a crawling size tunnel. this is the beginning of a route of tunnels and passages that eventually re-enters the main passage closer to the large room. the re-entering part is a narrow squeeze, and is therefore referred to as the "birth canal".

also, just inside the entrance to the cave, there is another side passage (which actually goes straight when the main passage turns right) that leads to a drop-off to a lower part of the cave. a couple spikes have been put in the floor near the edge, and people will rappel down. from there, they join the route to the birth canal more than half-way along it.

anyway the adventurous guys were going to do this route while the rest of the group waited for us. someone in the group i think had done it before. we started the first crawl, and just where i was partly submerged in rather chilly water we stopped--with people in front of and behind me--to decide whether we really had time to do the whole thing. we decided not. but i had learned where the beginning of the birth canal route was.

here's how i told the next part of the story in an email:

that email was written the day after the cave trip. we had gone on the first day the cave was open after the winter, and the trail mix had obviously not been there long, so it must have been dropped just that day. i remember a bit of exhilaration from successfully navigating the unknown. the other two guys hadn't even been in the cave before. see, it is not just a continuous tunnel, several times it opens out into rooms with multiple exits, so we didn't know if we were even going the right way until the very end. at one point, we chose which way to go based on some mud on the floor that looked out of place, presumably tracked there by the group that had just been through. i wanted to do it again soon, so as to remember the way, but that didn't happen.

the next time i did it was this year on my birthday, june 27, over four years after the first expedition. it did take us a while to figure out which was to go a couple times. here's the before picture, esther, me and laura. we didn't get an after picture because the camera stopped working when we got out. (it had taken a hard knock and sustained visible damage when my backpack got dropped, but my theory now is that the reason it stopped was condensation upon leaving the cool cave for the humid outdoors. it now works again. i took it apart and put it back together, but i'm not sure i actually fixed anything other than airing it out.)

anyway, we did it, and a few weeks later i returned with laura and lance and the route fresh in my memory. here's the before picture. this time we left the camera in the car, but i did take a compass and a piece of paper, and here's what i wrote (image. see the muddy messiness):

Birth Canal
begin route
slide down slope E.
13:20 begin crawl ~25' S. then climb up
and W. climb down
13:31 SSW boulders then down

then sharper rt.
then bigger to E, then wet
then option drop and sitting room
then rt. (S) and down 13:46

then tricky down then left
(W) up steep slick
easy big crawl W. then S,
then W and opens up standing
3 choices, turn rt. (N.W.)

option climb up on left to see
rappelling place. 14:16 rest 14:36
continue walk N.W.
crawl (small) NW then NE then U-turn
and other turns, then N. into
standing dome room. 14:53
again crawl very small NW then N into
another standing room then crawl NW
then right turn (CAVED IN)
backward crawl into
standing room 15:14 going back
the way we came in, out of
the last crawl 14:02. Think
the "cave-in" (not cave-in but dirt
and debris washed in, sticks, leaves,
small rocks etc.) was right before
the difficult pull-up (w/ no place
for feet) place, which leads into
a high ceiling room, then brief
crawl to standing slope up to
birth canal exit to main cave
massage (w/ volcano-like marking
on wall)


so we had entered the cave and i showed lance the rappelling spot from above. then i think before starting (certainly later if not then) i showed him the place where the birth canal re-enters the main passage. then we started the first crawl at 1:20pm. we took a break after about an hour when we got to the biggest chamber on the route, and lance and i climbed up to where we could see the rappelling spot (i think lance had left something hanging there). he found a glove and some rope (which stayed in the back of my truck all semester.) we were damp from a couple places where you have to crawl through standing water, by the time we resumed the hike i was getting chilly. (we had waited at the same place in june because we caught up with a larger group of guys in front of us, who were smoking cigarettes by the way.)

so three more crawls, with a couple little closet sized dome shaped rooms in between. the last crawl is the smallest yet, as in can't turn your head from right to left with the helmet on, and pretty slow going, centimeters per squirm. but we're getting close to the end, probably more than 90% through the whole route. and this is where it's about to get a bit freaky.

so we're in this tight tunnel and i turn a corner and the way is blocked. i look around, i must be missing something. but no, it's blocked, and newly so. i am in this little tunnel where i can barely move, and there is a bunch of dirt and little rocks, some of it right over my head. as in it could easily collapse and bury me. so i yell (but quietly...) back to lance and laura that we have to turn around. of course they think i'm kidding at first, but we back on out of there. probably less than 10 minutes before i'm back in the last standing room place, but it seemed longer. anyway, this is freaky not only because i was in this tight tunnel with loose sediment right over me, but also because we had just gone that way a few weeks before.

in retrospect i think that last tight tunnel was tighter in august than in june. the floor there is loose rocks like a stream bed, and maybe more had washed in. and i remember seeing several leaves and twigs on the floor in the little dome closets. of course water is what makes those tunnels. and apparently quite a bit of water had flowed through there quite recently to plug up the tunnel with all that crap. i sort of wish that after getting back to the main passage we had gone to the other end of the route and gone in to see the other side of that pile of stuff. anyway, a bit freaky, but a memorable experience. here's the after picture. and that's what i did last summer.
