Hope Martin Earth Cache
This cache is located in Hope Martin Park in Waterloo,
Not far from the Black Hawk Creek.
A glacial erratic is a piece of rock not native to the area in which it has come to rest, hence the name
"erratic" or errant location. These rocks were carried often hundreds of miles to their
current locations by glacial ice. This region of Iowa was covered by glacial ice four times in
recent geologic history. The most recent glaciation occurring 14,000-12,500 years ago when what is
now called the Des Moines Lobe of the Wisconsin ice shield reached its furthest south
by what is now Des Moines, Iowa. People familiar with the land in this part of the state,
geologically referred to as the Iowan Surface
As the glacial started to melt, the water from started to form the rivers and creek at surround the area.
As the glacial melt they left the erratic’s across the area. The glacial left from very large to
from very small boulders thought out the area.
During the times of high water at the Black Hawk Creek.
