This painting is approximately 12×18. It was sold through the Groveland Gallery in 2018. The reference photo I used was taken on a hike with my kids (Scott, Ryan and Jenna) about half way down 4 Mile Trail from Glacier Point. It was an amazing day with Yosemite Falls running very heavy since this was in June. It sounded like we were at an airport runway clear across Yosemite Valley!
