Spring (late April - June) Mild days and cold nights interspersed with rain and occasional snow.  Valley lakes usually thaw by late May depending on snow-pack with snow levels remaining just above the valley elevations until mid-June.  Valley wildflowers begin blooming as the snow melts peaking in June and July.

Summer (July and August) Warm days and cool nights prevail, with afternoon thundershowers common.  The snow level gradually retreats, with divides between the mountain canyons free of snow by August.  As the valley wildflowers fade, canyon and alpine wildflowers peak.

Fall (September - November) Sunny days and cold nights alternate with rain and snowstorms.  Aspen and cottonwoods change color in late September and early October.  As snow becomes persistent by late fall, elk move to wintering areas at lower elevations.

Winter (late November - April) Snow blankets the mountains and the valley, with accumulations of ten feet common in the mountains and two to five feet in the valley.  Between storms, sunny days and frigid nights provide perfect conditions for winter photography, wildlife viewing, snowshoeing, as well as downhill and cross-country skiing.
