The Upper Missouri River EarthCache Trail will formally open on Aug. 23 at 8:30 a.m. with a free 5-mile canoe trip to find cache sites.
The EarthCache system represents a new way to interpret the geological features of the Upper Missouri to visitors on river trips. EarthCaches can be located with GPS units, giving visitors access to information on the resources of the river miles from the nearest ranger.
There will be free introductory presentations given at 7 p.m. on Thursday at the Lewis and Clark Interpretive Center in Great Falls and Friday at the Missouri Breaks Interpretive Center in Fort Benton to explain the EarthCache Trail.
Signups for the canoe trip will be held during each presentation. There will be 20 canoe trip spaces available. There is no need for prior boating experience.
The trip will begin at the fairgrounds in Fort Benton and go downriver about 5 miles, allowing for participants to find EarthCache sites along the way.
For more information, call the BLM Missouri Breaks Interpretive Center at 406-622-4000 or 877-256-3252.
