At St. Mary's Glacier, Colorado.
Though the hike is short, the incline is steep. Altitude is around 10,800ft (3290m), so I was out of breath climbing up! Wore Microspikes on my boots the entire way. Was around 32°F (0°c). In the summer, this is one of the more beautiful views in Colorado, and easy to get to, but come early to get a parking spot!
