Undertow - Deer Valley, UT - 2026 - Top to Bottom MTB

Bike: 2024 Santa Cruz Bronson Carbon Date:8/19/26 Conditions: Perfect. Last twilight of the season and the dirt was hero. Temperature was also very nice since it was later in the day. Trail Notes: Black Diamond flow/technical trail. One of the Crown Jewels of DV in my opinion. There are some very fast and flowy sections of this trail that are just a blast. There is a spot where it merges with Regulator and you need to be careful to not hit anyone coming into the merge. Berms are huge and plenty. There is a steep drop with an alternate route (@2:37), but the drop is super fun if you can handle the steepness. It's a great way to end the day after lapping the upper half of the mountain
