This is smooth cliffbrake. Probably. Ferns are not my forte. There are so few of them around home, and I haven't had enough chances to learn the identification keys. The result is images that sometimes don't have the necessary clues. This time I needed to be a lot closer, so we would know for sure how much fuzz there might be on the leaflets. But we will just have to go with smooth, and enjoy the image of a pretty little fern clinging to the rock face. Smooth cliffbrake does that in AL, AR, AZ, CO, CT, DE, FL, GA, IA, ID, IL, IN, KS, KY, MD, MI, MN, MO, MT, ND, NE, NJ, NM, NV, NY, OH, PA, SC, SD, TN, TX, UT, VA, VT, WA, WI, WV, WY, AB, BC, MB, NT, ON, QC, and SK. Adams Co OH, 10/2/21. Maidenhair fern family, Pteridaceae.
