This was the third map I purchased from Calico, unfortunately all there are up to now. Whether they provide up-to-date detail like that of the Lagunas, or a fairly complete overview of a larger are like the most recent one of the Southern Sierra - I find them extremely helpful in planning our next hikes and/or weekend trips. And the water- and tear-resistant material promises a long lifetime even when heavily used; I hope to see many more new products in the near future!
