FATMAP difficulty grade
Silent But Deadly is a great place to find steep, cold, powder days after a storm.
You will want to beware of rocks and pecker trees though, they can throw off your mojo in here.
Head to the D Route gate and basically follow the North side of this line, as it paralells the upper third of Colter's.
You will have lots of nice hop turns through steep trees.
Be mindful of where you are, it is possible to go too far right and miss your clean exit back into Colter's.
