To Lake Katherine from Cowles. At the stream crossing, there is a path that continues on the right side and doesn't cross the stream. This is apparently a fishing path -- don't take it. Cross stream. Come to intersection of 261 and 254 which is marked. 254 actually takes you away from Lake Katherine for more than a mile so it is over 2 miles farther than 261. 254 is a fine trail, and there is a beautiful vista just after turning back in the right direction to Lake Katherine. 261 is not maintained by the forest service. It is a fine trail, but there are 12 downed trees to straddle and get over. (2008-08-30). My wife is 5’ 5” and didn’t have much trouble. On the other hand, there are a few downed trees across 254 that will only get cleared away when volunteers get to it. (Actually, a couple of volunteers were working on it the day we were there.) 261 is much steeper, and 254 is much longer. There are a lot of grouse along 261. Most trail intersections in the Pecos wilderness are marked quite well, but at the top of 261, where it merges with 254, there are NO trail numbers marked: The only sign says that this trail (which is 261) is no longer maintained. Thus, if you are walking along 254, you have no idea what the other trail is and you can mistake it for another trail on a map. Speaking of maps, older topo maps don’t show 254, and some of the newer maps don’t show 261. The last couple of miles to Lake Katherine are steep with lots of switchbacks. I tried dry and wet flies, a spinner, and power bait at Katherine without even a nibble.
