This EARTH CACHE is located along the USFS Fire and Ice Interpretive Trail. The trail is a ¼ mile loop of gravel and ledge rock. This is a day use area with a picnic table, but not toilet facilities or water.
As you walk along this trail, read the explanations of how fire and glaciers – two opposing natural forces- have shaped this landscape.
Our focus for this cache is an erratic boulder along the trail that we have nicknamed THE WHALE. You will see why as you approach it.
About 10,000 years ago a glacier (a sheet of ice and snow up to a mile thick in places),pushed through the area. As the climate warmed and the glacier retreated, it left behind evidence of its presence. THE WHALE is part of this evidence. It is called a glacial erratic.
Glacial erratics are rocks that deviate from the type of rock native to the area in which it rests. The rocks were carried to their current location by glacial ice. Erratics can range in size from pebbles to 16,000-ton boulders. THE WHALE weighs about 85 tons.
Although some of the glacial erratics were transported great distances by the glaciers, this one was not moved very far. Evidence of this is that it still is angular and there are few scars from movement. There is also evidence that the boulder is still changing. Look at the base where large chunks have fractured off and the surface is being eroded by lichen.
