This is a sad list to compile. Beginning in 2005 an intrepid group of interested people located big trees in Los Alamos County, excluding Los Alamos National Laboratory lands. They found the biggest evergreens in Cañon de Valle and at Cañada Bonita. The Las Conchas Fire in 2011 killed most of those trees and many of the second and third runners up. This list seems a pale shadow of our previous champions, but they are our trees to love. Read more Big Trees of Los Alamos County 2013 ›
