Anyone who has hiked with me to Crater Lake or Mount Sopris or up a fourteener has heard me spout some fun facts about pikas.
These itty-bitty mammals, whose chirping calls announce that you’ve made it into the highest of the high country amid the talus and tundra, are fascinating little creatures. They’re among the highest-living mammals on Earth, making their homes up there year-round, building underground lairs where they stay – far beneath the snow and rock – through the long winters.

Global warming poses a unique threat to these guys, because they need cold alpine temperatures, can only go as high as the mountains go and can easily die from overheating.
