I recognized Little Colorado Canyon the instant I saw your paiIting. It brought back memories of several times i have visited it; and, especially the time when you were a little girl. Yes, no railings and straight down was indeed scary.
I like the painting. when I really try and find a shortcoming, I wonder a bit about the mountain range floating on a lake in the right upper background, just below the horizon. Maybe just my poor vision. Love, Dad
