I literally went “holy crap!” In shock when I saw that! Last year this spot had a wash out that you could lose a Prius, or two into… Someone got Serious about fixing it!
(Trail was created for, and gets a LOT of traffic from dog mushers, being one of only two easy outlets from our hill into the back country… Such trails tend to get a lot of care put into them.)
Just wish I knew who to thank/help re-pay… had to be a bit spendy, and a fair amount of work.
