School Begins!

School has begun, which means that I will have less time to go to the field. Thus, I must pick the areas I will go for fracture analysis wisely. I figure that the snow will hold off until late October, which gives me a little less than two months to finish up.

This week: plot up all the sites I have visited, and see where coverage is lacking on the anticline.

Goose Egg Formation

Goose Egg Formation

The Goose Egg Formation is exposed all along the top of the anticline. It often appears with thin beds and massive beds interlayered, as seen in this picture.

Breccia

Breccia pipes or collapse breccias are seen in the Lower Kane Cave that is adjacent to the Bighorn River on Little Sheep Mountain Anticline, and along the road cut that was created by the Bighorn River and further excavated for the railroad intrusion, there are other possible breccia pipes or collapse breccias.

• Trending to the north
• Large boulders within brecciated matrix

Fracture & Joint Analysis

Fracture analysis was performed along the Bighorn River and railroad cut.
