When driving along the Tioga Pass Road you see a lot of outstanding scenery. Unfortunately, there are not a whole lot of turnouts in some of the scenic locations. Siesta Lake is one such exception. This small lake is located on the north side of Tioga Pass Road at marker T8. This little lake was created by a moraine on a cirque glacier that was located on a ridge above the lake. The moraine acted as a dam and created this picturesque lake.
