> Be aware that the location of the Cottonwood Lakes trail is incorrect on the USGS topos (out of date) for the last couple of miles to the trailhead, and by extention on GMAP4 and ACME, so don't let that confuse you.
Glenn, thanks for pointing that out! Until now, I hadn't noticed, but you are right. Checking the map versions, some show the trail crossing the middle of Horseshoe Meadow to Trail Pass, and others don't. And those that do show it are not accurate.
