Did you find the rock in its present form? or did you have to chip residual rock away from the top and bottom to reveal the natural shape of the folds?
That’s awesome, Callan! We were hiking in the Galatin forest last month, and I had no idea that the rocks beneath were so old. Or so beautifully folded.
Hi Heather! Great to see you out here, milling about in the geoblogosphere. The Gallatin NF includes several other areas besides the Gallatin Range — so you may or may not have been hiking over these ancient rocks. Regardless of age, though, the rocks beneath all Montana,s mountains are interesting!
