According to World Wildlife, pikas can be found in rocky areas called talus. They can be described as alpine regions. The alpine regions in Canada for these pikas are from southern British Columbia to southern Alberta.
In the U.S. they can be found in these states: Oregon, Washington, Colorado, Utah, California and New Mexico.
Since they are temperature sensitive, pikas' populations significantly increase as the elevation rises. In Canada, populations are seen from sea level to about 9,842 feet. However, in New Mexico and southern California, populations are generally not seen from 8,202 feet.
The small animals can sometimes be seen along the trails and roads of several national parks, such as Yosemite National Park, Yellowstone National Park and Craters of the Moon National Monument.
