Grimes Point Archaeological Area


Grimes Point is an archaeological site which was listed on the National Register of Historic Places in 1972. It is located seven miles east of Fallon, NV on the north side of U.S. Highway 50.

During the Pleistocene Epoch, this area and most of northwestern Nevada, was covered by ancient Lake Lahontan. Over the last 10,000 years, the level of ancient Lake Lahontan fluctuated widely, at times drying up completely. When above water, the Grimes Point area would have been marshland with a wide variety of wetland plants and animals available for use by prehistoric populations. Grimes Point was first visited by Native Americans perhaps 8,000 years ago or more.

Grimes Point is a field of basalt boulders that are covered with a glossy black patina, commonly called desert varnish. Many of the boulders are covered with pecked or carved rock art called petroglyphs. The antiquity of many of the petroglyphs can be evidenced by how varnish has completely repatinated the carved surfaces.

Visitors today can view examples of petroglyphs along a 1/4 mile, self-guided interpretive trail. The trail was originally constructed by the Youth Conservation Corps and named Nevada's first National Recreation Trail in 1978.  Handicapped accessible restrooms and picnic facilities are available at this popular stop on U.S. Highway 50.
