Seconding MTB Project, Trailforks is also great. Hopefully the following links work (posting for mobile)
Thanks! Utah looks about what I was thinking, but do you agree with those results for CO/WY? The site includes both full trails and sections, makes me wonder if the userbase might undervote certain trails...
(Also, is that Singletracks site the go-to site? Do you use the Lite App? (it gets not-so-good reviews.) I've been looking at MTB Project quite a bit, but otherwise just hunting through local sites))
