May 13th - . 34" base at Bear Lake. Most all lower elevation trails are free of snow and in good condition for spring hiking. Snowshoeing , or some type of boot traction system ie... yak tracs - ice trekkers is still recommended up high. Lakes are thawing would not advise any more crossings. Becoming more spring like. We think spring is finally here to stay. Trail ridge opens on or before Memorial day.
