Rock Sandstone near 雅哈垭口

I took a self-driving tour from Chengdu to Ganzi in October this year.
This was the first photogrammetric model generated from the photos near 雅哈垭口（I don't know how this place into English).
For the photogrammetry work, this model has not been delighting yet，missing some downside part.
At that time,I don't know to capture the HDRI. Nevermind, I shall go there next time in the future.
