The two times I've done the MR it took me about 40 minutes in the summer. Actually, the first time it took over an hour because I got lost in the brush. The second time I went up the north side of the creek, not the south like all the books say- and made it to the ledges in 40 min. Depending on the snow level right now it could take much longer or about the same time if you get a pretty level snow pack.
