Our "typical" geocache container - 12" by 3" hidden in one of the only places it could hide near the brink of an unimposing-looking gravel pit.
This low-profile gravel pit may seem uninspiring to the untrained eye but take a closer look at the ground around the pit area. Embedded in the gravels of the pit are pebbles of "Nevada wonderstone" that were tumbled and polished by streams and by wave action along the shore of a lake that was last filled to this level between about 11,000 and 13,000 years ago. The common rockhound name Wonderstone refers to a colorfully banded rock - usually in shades of tan, red, orange and brown. This rock started out as a volcanic rhyolitic air-fall tuff, formed from a deposit of ash ejected from a volcano about 12 million years ago. The rock was altered by hot groundwater that deposited pyrite (FeS2 ) and quartz (SiO2 ). Rainwater penetrated the rock and oxidized pyrite within the rock to form "liesegang bands" of red hematite (Fe2 O3 ) and orange and brown goethite (FeO(OH)). Erosion broke pieces of the rock from its outcrop higher in the hills, and streams carried the pebbles to the shore of ancient Lake Lahontan where currents and wave action tumbled and polished the pebbles to their current condition.
