Mymathens 1969 journal 8 June 30 (cont.) Papa Leon Tree, 150+-ft., Dept. Lima, Peru. Carol Pearson had 32 small shermans, and I had 30 large folding shermans. We each took a gully between 2 hills and made our way up it. The weather was grey and overcast. I set 2 lines of 15 traps each. The first started at the bottom, where there were occasional rock piles or cactus. As I went up it became progressively rockier and more abundant cactus was growing. Soon the slopes were pure talus with occasional paths leading up it (for goat?). I set traps at intervals of about 20-25 paces, trying to leave the traps along rocks, or near protected places in rocks or cactus where it seemed mice might want to be. No definite sign of mice, but what appeared to be burrows weren't uncommon. The soil is somewhat loamy. Much of it appears to be tiny chunks of dark lichen. Lichen is prevalent on all the rocks. It is usually a darkish color. A few brightish yellows or greens are isolated in some spots. Carol found several fox droppings higher up. Below, in the river sand, mouse tracks could be seen. Apparently, tracks remain for a long while after they are made. The
