Looks like the final resting place of Clifford the big red dog

If it helps, I'd bet a good amount of money this is photoshopped. That tail looks absolutely not natural, and the overall picture has the same vibe as the "photo" of the 'Mt susitna sleeping lady' that circulated a little while ago, and that was photoshopped as well (google 'mt susitna sleeping lady photoshop' and you should find a 'leadstories' article fact checking that).
Photo in question can be found : reddit com /r/SighsUnzips/comments/fvb5hl/sleeping_lady_mountain_range_shot_from_drone/

I'm pretty sure it is photo-shopped, but that wasn't what induced the sadness. The sadness was induced by simply being reminded of Clifford :/
