Two anglers enjoying the World class fishing that western Montana rivers has to offer. 

Map showing federal, state, and private land holdings of core winter elk range around the National Elk Refuge (labeled as the FWS unit). Map was generated by the USGS. 

Jackson elk herd migrations around the National Elk Refuge are shown in dark blue (short-distant migrants) and light blue (long-distant migrants). Elk migrations cross federal, state, and public lands. The map was generated by the USGS using data from the USGS Data Release Kauffman and others, 2020.

Montana is known for its fishing opportunities, especially its cold-water trout fishing. Here, someone is fishing in Big Hole River, Montana. 

The Ruby River is a tributary of the Beaverhead River and anglers enjoy trout fishing here.  

In the same day, a female mule deer (left image), an elk (middle image), and finally a buck mule deer (right image) visited the same mineral lick in the Greater Yellowstone Ecosystem. The USGS is investigating how the aggregation of multiple individuals and species in mineral lick locations can influence wildlife disease transmission.
