Lake Siskiyou is beautiful this time of year.

About 200 miles north of Sacramento, the artificial reservoir — formed by a dam on the Sacramento River — is ringed by quiet beaches that offer a cool respite from triple-digit heat. The views of Mt. Shasta are spectacular. When I visited last week, I saw double-crested cormorants, ospreys and great blue herons soaring over the water and ducklings swimming with their mother.
