Once as imposing as the Rocky Mountains, only two peaks in the park crest higher than 4,000 feet now. Time and erosion smoothed rough edges and trees carpet the languid curves and slopes. Summer is the season of quick storms and steady birdsong, long hikes and easy daydreams. It is literally a breath of fresh air.
