A very easy trail, we went out there to test this XC70 my buddy built out of Baker Garage. Everything worked great, need a tougher trail haha. Mammoth Gulch is still cool and connects to a bunch of other stuff.

Calvary 4-Wheelers ran this trail as a back way in to the Dakota Hill area. They haven't run a bulldozer over the road in a while and it is getting a little bumpy but still passable in 2wd with careful driving. The weather was cold, windy, wet and rainy so I did not get out and take any pictures.

We took this trail on our way to Kingston Peak. Basically the road is a connector to other trails in the area. It is rocky and nothing technical. There were some nice dispersed camping spots along the way.

ran this trail after I finished kingston peak, pretty bumpy and plenty of space to pass, there are a few spots with views but the big reason to come here is to camp, I was just passing through but it still looked like there were plenty of spots (all of which were taken). watch your wheel placement when you move to the side to allow others to pass, I ended up pulling two vehicles back up onto the road after they had slid off. I give this trail four stars because there isn't that much to see and there are a lot of people (As per usual in colorado).

Dirt road with seemingly a lot of folks putting their vehicles on dirt for the first time. Pretty much every time I take this trail I have to take it super slow as I get behind someone that will not let me by. Be patient with them on this one, we were all n00bs once.

Really a connector trail, full of AWD Subaru type vehicles. Kingston was closed.

The Gate is open to Kingston Peak. The wildflowers right now are beautiful. Mostly dry on all trails.

Same as the review by Rick Boyett below. Open up to the Kingston Peak gate, which is closed. Some puddles from rain, but nothing more than 1/2 ft to 1 ft. I didn't see any snow myself.

Wide open, up to the Kingston Peak gate, which is still closed. Some bits of snow here and there but nothing serious.

LJ on 37s, dual lockers, and another LJ on 33s, dual lockers. The current snow conditions are quite deceiving. Up until waypoint 5, there was only a few inches of snow on the trail. At that point, exactly at the pullout, was a Ford Raptor stuck in a wind blown, sugar snow drift. They did not have a shovel, or any other recovery gear. They were attempting to free themselves by tossing rocks and pine branches under the tires. We were able to give them a quick tug out with our recovery rope, got them turned around, and continued on our way for about 100 yards, when we ran into another buried pickup truck. The time a dodge. Again, we quickly whipped them out of the drift and again continued on. We were able to complete the entire trail, but the snow beyond waypoint 6 is extremely deep, dry sugar snow that will swallow regular suvs and pickups. Anything not on large, aggressive tires will have major issues like we saw.

For being so close to Denver, this a great trail/area where you get to really experience the alpine environment.

We headed up here to get to Kingston. The trail is open all the way through and doesn't appear to have taken any damage from the rains lately.
