So you like 'em skinny, eh?Spend some time in North Wash, and you'll get a plentiful dose of skinny canyons. Some people refer to any canyon who's bottom is less than your arm-span as a slot. What do you call a canyon that is not as wide as your arm?There are a variety of adventures available in the area. North Wash canyons are cut into very soft Navajo sandstone, and vary from narrow to very narrow; and from friendly to not-friendly at all. Somewhat surprisingly, the nastier slots seem to have smaller drainages, but cut to the same depth - and thus are skinnier. You want to see skinny - take the 10 minute walk to the end of Sandthrax, where a quite substantial drainage exits through a 2" crack. Ominous. There's something for everyone with an emphasis on fun! The canyons themselves and the moves involved in climbing through the bowels of the earth are fun, when you are mentally and physically prepared for the experience. There are fun things to do in a few hours, with or without a rope, and routes that will keep your attention all day. Most routes involve quite a bit of climbing, and many will test your ability to conjure up a zen-like calm - even when you really don't want to.
