We dropped down to upper Crabtree lake and around the north side of the lake. There is a use trail that continues west up the draw from the west end of the lake up onto the bench. The trail then cuts back up towards Discovery peak. The trail is decent until you get heavy into the rocks where it becomes intermittent and you are pretty much scrambling up towards the top of the ridge. Once you get up on the ridge it opens up considerably and the climb isn't that bad up towards the peak.
As we read in other places, the short descent to the main trail is pretty steep and a bit tricky. Part of our group cut back west around the peak and ruffled some feathers with sliding rocks onto the main trail. The rest of us kept east a little bit to a spot where the trail was clearly visible below and we could give some advance warning to passerbys.
