Since the beginning of the USGS Repeat Photography Project in 1997, Grinnell Glacier has been photographed from the summit of Mount Gould multiple times, documenting the glacier’s retreat and the enlargement of Upper Grinnell Lake.  You can view previous images from this vantage point, as well as the entire collection on the

There is a short window of opportunity to complete glacier repeat photography.  Scientists must wait until late summer, when seasonal snow has melted from the glacier surface and glacier margins can be identified.  This is also the time of year when weather and forest fire smoke can hamper photography and hiking.
