(this warmer weather is bringing everyone out!)
A hike late yesterday of the Newton Trail showed it in good shape. There's a bit of mud scaling the hill, but nothing insurmountable. The brook is in full spate and quite a fun crossing.
Connecting to the Cascades trail to head down to the Lodge, we quickly discovered that even the switchback spur is a difficult, slithery descent. The mud, the leaves, the rapidly disappearing snow cover all combine with the steep slope to make it a tricky, possibly muddy, hike (slide?) down.
(This is especially true if you're under four feet tall!)
Unless you're really up for this, we'd recommend descending the Cascades trail from the other end!
