A slope formed by an accumulation of rock debris, often at the base of a cliff or steep slope. Talus can look almost as if it was poured down the slope. Lots of scree beneath small cliffs mean rotten rock or older mountains, while firm granite faces often have little scree deposited. However, the Backpacker editors differentiate them for clarity. Scree comprises rocks from pebble size to head size.
Talus comprises rocks from head size to almost sofa size.
For traveling lots of it, stitches should be sealed with a resistant product like Seam Grip, Shoe Goo or Aqua Seal, so the rocks don't chew up the exposed threads. Scree chews up the smooth outer finish, and the leather then becomes less waterproof. Ankle gaiters help keep rocks out of your boots. The navigation differs for a talus field and a scree field. When navigating talus, aim for steady rocks, typically bigger ones that look like they've been around for awhile.
