In 2010 the northern section of the route for the Butte 100 Racecourse looked very different to what it does today before organizers decided to make the route "more compact".

The southern section of the route has remained very similar. However, since 2010 there have been trail re-routes/additions on Skeeboggan, Bear Gulch, and 8-miles of Hell. Placer/Eagles Nest Trail did not exist back then. The route also went up the steeper Grading Camp Trail, where as now it goes up the Chimney Trail (Upper Grading Camp).

Nice rock formations. Trail is clear of downed trees as of July 2022.

The worst sketchy part is just over the hill from the parking. That is unless you take the wrong turn like we did and head up and over the steep pipeline trail! It’s straight up and straight down.

This makes for a loop option to drop down to the Blacktail Ridge trailhead. From there you can take Blacktail Ridge to the Beaver Pond trail, then come back on the CDT.

90% of what is shown as this trail is a paved street! There is only half a mile of double track at the very start of this, which might be rated blue. The other four and a half miles is easy pavement!

Trail was cleared and mostly dry. The Northside of the main summit had 5-6 snowy switchback patches.

This is a fun trail that looks like it gets a lot of traffic from dirt bikes and ATV's. For me the sketchy part about this trail is deep sections of loose sand. I think most intermediate level riders would be fine riding this trail because it's not too difficult if you just take it slow.

Rode from TH at Hwy 90 as an out-n-back. 5 miles up takes you to ridge line with excellent views of Butte MT and the valley. Trail is very well designed with switchbacks and nice tight single track. Trail was damp in places due to recent afternoon rain showers.
