Has any of you spent much time on the western part of the Tuckup Route in Grand Canyon? Can you tell me about the trail conditions and how far you were able to walk in a day? I'm scheming about linking a few of the canyons in that area, and wondering how long it would take. It's hard to tell from the topo maps and aerial photos whether it's a walk on a packed trail or a slog through soft sand, up and down gullies.
