Yep! Glad you recognized it!
Gorgeous place, but I haven't been there in 30+ years, so I was guessing as much as recognizing. The only climbing spots I know in your general area are Seneca Rock and Carderock / Great Falls, and it definitely wasn't the latter, so...
My former husband was a rock climber. I tried a couple times but am way
too scared of exposed heights. What I did get into was climbing some of the easier 14,000 foot mountains in the Rockies.
