Did another water drop today, this one over 10 miles round-trip. This one had shown no use since it was last stocked. We split into two groups and the other group checked a drop up a different canyon that seems like it had a little bit of use, but not much. Nearby is yet another drop that has in fact been getting regular use. There are hundreds of combinations of routes through the mountains and the ones people use change, often without rhyme or reason, so we try to check all of them regularly.
