Lake is a deep alpine lake at an elevation of 5,000 feet on Huckleberry Mountain.  The trail is close to 3 miles long with an elevation gain of about 2,000 feet.  This is a good late season hike to see wildflowers in bloom.  Snow and ice around the lake can often be seen clear into July and it is advised to check with trail conditions before heading out.

The trail starts off on a brushy previously logged area mostly following the ever changing Tenas Creek.  As the trail begins to climb through along the creek listen for Tenas Creek Falls and you will see it up ahead.   When you near the wilderness boundary you enter dense forest with stands of old growth trees.  The trail will climb steadily until you reach the boulder fields and alpine meadows with beautiful wildflowers along the creek.

Just before reaching the meadows on the southwest side of the lake, begin to listen for the waterfall that forms from drainage of Boulder Lake, this is the headwaters of Tenas Creek.  As you begin to circumnavigate the way trails along the lake you will see a large boulder field to the southeast, just above this boulder field at about 300 feet higher is Pear Lake.  Near Pear Lake was the location of the old Huckleberry Mountain Fire Lookout.  Opposite the boulder field to the north is Hurricane Peak Ridge.  A steep almost 1 mile way trail branches off and heads up to the ridge.
