Leonard Rockshelter, a prehistoric archaeological site in Pershing County, Nevada, preserves a long record of intermittent human use in a sheltered limestone formation. Artifacts first recovered there in 1936 and collected again in 1937 included shell beads, feathers, and wooden projectiles. Radiocarbon dating and later analysis revealed at least three distinct periods of prehistoric occupation, historic material from the 19th century, and a sequence extending from about 9249 BCE to AD 1400, soon after Lake Lahontan receded from the region. A notable find was an infant burial from about 3500 BCE in a basket that later became fully carbonized. The site was named for Zenas Leonard.
