Mount Whitney Fish Hatchery - An anomaly amidst the desert landscape, this vine-covered Tudor style three-story building is the Mount Whitney Fish Hatchery. Resembling an old European country estate, the ponds, trees, and picnic area afford a lovely respite from the desert heat. Built in 1917 from native stone, the site is now listed on the National Register of Historic Places. The hatchery is significant not just for its beautiful architecture but because it marked the beginning of trout management in the Eastern Sierra. Outdoor recreational activities, such as fishing, have been part of Eastern Sierra history for more than 80 years and continue to play an important economic role. Known for its trophy trout, the Eastern Sierra attracts fishing enthusiasts from all over the world. Still in use today, the hatchery's primary work is the production of trout eggs. Nearly 10 million spring- and fall-spawn brook, brown, and rainbow trout eggs are produced annually.
