Start at the south end (the highest elevation), where Tank Seven Creek Trail #480 intersects with the CT - Segment 16: Marshall Pass to Sargent's Mesa.
Although short, Tank Seven Creek Trail should be memorable.
The first half, approximately, is mostly demanding rock gardens and other features, so it's a black diamond technical stretch. Technically talented people will love it; those of us less talented shouldn't mind enduring it, because it isn't that long.
The second half, approximately, is soothing, flowy descending through a beautiful landscape, mainly groves of trees, until almost the northern end. It's perfect for intermediate mountain bikers, but advanced and expert riders should like it too.
Finally, there's a short climb before the trail reaches Marshall Pass Road.
Watch for the occasional motorcyclist.
