Winnemucca Lake
dry lake bed in Nevada with petroglyphs

Winnemucca Lake is a dry lake bed in northwest Nevada that features the oldest known petroglyphs in North America. Located astride the border between Washoe and Pershing counties, it was a shallow lake until the 1930s, but was dried when a dam and a road were built that combined to restrict and block water flow. It was formerly designated as a National Wildlife Refuge, but its status as a refuge was removed due to the lack of water.
Winnemucca Lake is home to several petroglyphs long believed to be very old. In 2013, researchers dated the carvings to between 14,800 and 10,500 years ago. Either date would make them the oldest known petroglyphs found in North America. The carvings lie within the Pyramid Lake Indian Reservation.
Note: There is another lake, having the same name of "Winnemucca Lake" in California, near the Carson pass (coordinates: 38°40'10.80"N, 119°59'36.59"W).

Why this record matters
The phrase “dry lake bed in Nevada with petroglyphs” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q8025576. VIAF identifies the subject as 315527135. Authority coordinates are 40.111, -119.341. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2013.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
