The new Craig Thomas Discovery and Visitor Center is located in Grand Teton National Park along the Snake River, snuggled up against the Teton range at Moose Junction, a few miles outside Jackson, WY. The building construction utilizes materials consistent with the landscape and climate, with massive log frames supporting a glulam rafter roof system making up the primary gravity load system. A vast sloping window wall system looks out to the Teton range beyond and is supported by custom steel mullions. The lateral system is a combination of concealed braced frames, moment frames, and wood shearwalls. This structure posed special challenges with roof snow loads approaching 300 pounds per square foot combined with the high seismicity of the area. The Visitor’s Center is open to the public year-round and draws over half a million visitors a year.
