At this time of the year, the Garter Snakes come out on the trail to try and soak up the sun. They are trying to warm up their cold-blooded body. They are very lethargic because they are cold. They can’t move very fast and it takes a lot of energy to make quick moves. It’s a risk for the snakes to come out in the open in this way as it makes them easy prey for migrating hawks.
