Grimes Point Petroglyphs, near Fallon

To understand Grimes Point you have to picture the water. During the last Ice Age, much of northwestern Nevada lay under ancient Lake Lahontan, an enormous inland sea. Over the last ten thousand years that lake rose and fell and finally shrank away, leaving behind the flats, terraces, and shorelines you can still trace across the valley.

When the water was high, the Grimes Point area was rich marshland, full of the plants, birds, fish, and game that drew people to camp and hunt along its edges. The boulders that now sit in dry desert once stood near a living shore, which is why this became such a gathering place.

The petroglyphs at Grimes Point were made by pecking and carving through the dark desert varnish to the lighter rock beneath, leaving figures that range from simple lines and circles to more complex patterns. Some are thought to be thousands of years old, among the older rock art in the region.

Archaeologists still debate exactly what the images meant, and the honest answer is that no single explanation covers them all. Some may mark hunting or gathering, some may be tied to ceremony or story. What is clear is that this was a meaningful place, returned to again and again over a very long span of time.

The self-guided trail lets you walk right among the boulders, with signs to help you spot the carvings and understand the setting, while asking every visitor to leave the fragile stone exactly as they found it.

A short distance away, a rockier trail climbs to Hidden Cave, a chamber hollowed out around twenty thousand years ago by the waves of rising Lake Lahontan. It got its modern name because the entrance is easy to miss; a group of local boys rediscovered it in the 1920s.

Excavations showed that people used Hidden Cave mainly as a storage cache, tucking away goods and tools roughly three to four thousand years ago rather than living in it. Because the cave is so dry, it preserved delicate things that almost never survive, from basketry and textiles to microscopic pollen, giving researchers a detailed record of how the land changed as the great lake dried up.

The cave is typically entered only on scheduled guided tours, so check ahead if you want to go inside, but the trail and overlook are worth the walk on their own.

This is the homeland of Northern Paiute people, and the Fallon Paiute-Shoshone Tribe lives in the Lahontan Valley today. The rock art and cache sites are part of a living heritage, not just an archaeological curiosity, which is why the request to look but never touch matters so much.

Wildlife here is classic high desert: jackrabbits, lizards, ground squirrels, hawks and ravens overhead, and rattlesnakes in the warm months. The old lake terraces still shape where water and plants collect.

Spring and fall are the kind seasons, with mild days and good light for seeing the carvings. Summer middays are brutally hot and exposed, and winter can be cold and windy, so time your visit for the softer hours of the day.
