OverviewEastern Sierra. These mountains are composed of some of the oldest metamorphic rock in the range. Much of this colorful rock is rotten and unstable due to all the ancient transformations it has been through. Nearby Mt. Morrison and The Great White Fang are well known for their loose tedious rock.
Mt. Aggie is a pretty simple class 2 scramble from all sides and can easily be done in less than a day. Staying on the ridgelines will probably save you from scree slopes.
There are outstanding views of Mt. Morrison and The Great White Fang to the north and west and south to the peaks over the McGee Creek drainage.

Follow the McGee Creek Trail southwest for .5 miles and break off directly up the sagebrush slope curving to the left where the slope eases and take the east ridge to the class 3 north summit, continue on to the main summit to the south.
