Lower Blue Lake is located at the base of Mt. Sneffels in the Uncompahgre National Forest, not far from Ridgway. Its increasing popularity with visitors has resulted in more use, and forest managers are trying to determine how many people are using the trail and the possible impacts. Meanwhile, local volunteers have launched a "Save the Blues" campaign to help encourage "leave no trace" habits on the trail. Adobe Stock/Krzysztof Wiktor
