EUREKA!!! A DRUMLIN FIELD IN MONTANA? EarthCache

This valley is the route of Highway 93. After crossing the Canadian border at Roosville B.C. the traveller immediately notices rounded elongated hills oriented to being somewhat parallel to the highway north of Eureka MT. These distinct hills, with a whale-shaped profile, are called drumlins which are an unusual landform found only on glaciated terrain. Scientists are not sure how drumlins form because they form out of sight under the ice. Many think they are created when highly pressurized water floods out from underneath glacial ice. Large amounts of water can build up under glacial ice, and sometimes it escapes at once. These cavities could then fill with gravel or till, the essential glacial product. It is also thought that perhaps they are waveforms similar to ripples of sand at the bottom of a stream. The drumlins orientation indicates the movement of the ice with the higher blunt end facing into the glacial movement and the thinner tails trailing off in the downflow direction.

The above coordinates will take you to a roadside information spot.

E-mail us the following information before logging your find:
(A) What is the direction of the ice flow?
(B) What is the height of one of the nearest drumlins?
(C) From the information board at GZ, what is the significance of "tadpoles"?
(D) Take a photo of you and your GPS with a drumlin in the background. Optional
