[3] Hidden Cave was not lived in, but used as storage site for goods and tools for the 2000 years of its survival.

Hidden Cave is located at a hilltop some 12 miles (19 km) from Fallon and east of Lahontan Valley.

Four generations of archaeologists have worked at Hidden Cave, demonstrating that the site was used for the storage of food, tools, and for the placement of a few burials.

[2]: 107–111  The cave was their secret until a local miner, Mr. McRiley, came in and mined it for bat guano, which was a high quality fertilizer.

[2]: 112–114  McRiley's account of the cave reached Margaret Wheat, a lifelong Fallon resident and archaeologist.

Wheat recognized the value and invited Mark Raymond Harrington, who had previously excavated Pueblo Grande de Nevada and Gypsum Cave, to investigate.

At the end of the summer, they put up an iron gate to prevent vandalism, allow people to see what they had discovered, and to allow future archeologists to explore.

[4] There was proof of high and low levels of Lake Lahontan, wet and dry climates, volcanic activity, and human inhabitant usage in the cave.

The main artifact category discovered were food remains including the pinon nuts mixed with cattail pollen.

Bulrush seeds were also found, whose fruits are harvested six weeks after cattail pollen around the same time as the Pinon nut.

The contents were used to infer the possibility that a 'second harvest' strategy was employed as a way to obtain undigested seeds from feces.

[3] Today, the Grimes Point area is a destination for hikers and wildlife enthusiasts, and is known for its accessible petroglyphs.
