Fort Collins, Colo., photographer Jeff Olson and his wife, Joanne Plager Burke Olson, recently made a wilderness hike to Mount Blue Sky Recreation Area, located on the Front Range of the Rocky Mountains near Idaho Springs, Colo. Mount Blue Sky, elevation 14,250 feet, is the most prominent mountain overlooking the city of Denver. Along the way, they visited Mount Goliath Natural Area, located within the Mount Blue Sky Recreation Area. The Mount Goliath Research Natural Area contains 160 acres set aside for the protection, study, interpretation and enjoyment of the Rocky Mountain bristlecone pine. The Dos Chappell Nature Center contains exhibits that interpret how living things adapt to the harsh environments of the subalpine and alpine tundra. The main attraction is the Rocky Mountain bristlecone pine tree. These trees are 700 to 1,600 years old, making them some of the oldest tree species in the world.
