A Great Basin rattlesnake (Crotalus oreganus lutosus) is coaxed into a plastic tube. This plastic tube allows researchers to safely handle the rattlesnake during biological sample collection.

After hiking to the location of the historic photo, USGS employee, Lisa McKeon, uses the alignment of mountains and permanent features to compose the same shot as the original.  Sometimes, determining the location can take a long time, requiring moving up and down a mountainside to find the exact spot.

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

Mangrove forest in Micronesia.

The USGS and partners are studying how mangrove forests in the Federated States of Micronesia may respond to sea-level rise over the coming century. Their projections will help Micronesian communities plan for the future.

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.
