The Eastern Sierras provide unique geological and environmental features. On this trip we will see towering columnar bassalts, boiling water hot-springs draining into a local stream, an earthquake fissure, and the carbonate tufas of Mono Lake. Hiking will be on Saturday and Sunday, with camping Friday and Saturday nights.
