In addition to the great long range views of Halfdome, the upper reaches of Lewis Creek basin held a remarkable surprise. There is a stunningly blue pothole lake that we encountered on our way over to Hutchings Creek basin. The first photo is of the last large lake in upper Lewis Creek basin (the pothole lake is hidden in the area at the upper right of the first photo below the most-distant snowfield). Then, there are a shots of the pothole lake.

The Hutchings Creek basin is gorgeous, and I wish we’d spent more time there, but after a jump into the upper part of the basin above Florence Lake (views from the Hutchings/Florence ridge captured Halfdome again), we needed to keep moving if we were ever going to get to Blue Lake.

From Hutchings Creek basin, we took the saddle northeast of peak 12,113 to get into the basin of the Lyell fork of the Merced. Both this basin and Hutchings could keep me happy for many more days than the 3 nights we spent in that area. Both basins are a definite must for a return trip! Although we did not camp there, the west side of the long lake directly below Mt. Ansel Adams is splendid (see photo). A few shots of the area give a flavor:
