Alaska is too cold for most herps. Only the Wood Frog and Western Toad have enough records to make the list. Wood Frogs survive the winter frozen solid. June is the busiest month.

Peak and shoulder ratings are rough guidance, not a schedule. Weather, elevation and the year can shift any species by weeks.
Rare and protected species are left off on purpose. Look, don't take, and never handle a venomous snake.

Keep Herp Calendar free
Hi, I'm Nick. I built Herp Calendar on my own and I keep it free, with no ads. If it has helped you find a herp this season, a small tip goes straight into the hosting and the data work. Only if you can spare it. Either way, I'm glad you're here.
