Thanks Virginia for your comments. After a bit of research, I've found that it is not Diphasiastrum sitchense, but likely Diphasiastrum complanatum, which is found in the Kootenay area as well as to the west from Oregon to Alaska.
Since it does not resemble the one photo by robertduval14, with the common name of Northern Running-Pine, I will have to look up the other three complanatum entries.
Research for another day.
Here are some more photos taken from the same location and on the same day of my two submissions to the Fan Clubmoss entry. If there is anyone out there who can tell me which category it belongs in, feel free to let me know.
Thanks.
