Monument Creek: Schist Narrows
Schist Narrows: a geologic rarity! Schist is the stuff that doesn't belong in the southwest. It's not sandstone. It's weird metamorphic rock that seems marbled and smooth, dark and evil, even mysterious. Making it more mysterious is the fact that it's so old and only exposed in some of the deepest parts of the Grand Canyon. You've got to reach far back in time to see schist. Even more rare is a slot canyon with flowing water and schist walls. Such a place exists only in Monument Creek, by Granite Rapids, deep in the Grand Canyon. The black is schist. Pink stuff is granite (hence "granite rapids"). Monument Creek is pretty but the rocky surface makes hiking a trudge. Also, beware of schist. Shoes do not stick to schist and you can just slide right down the slick surface. It's not like any other rock I've been on. Smooth schist is like ice in many ways.
