We may have run into Bob on the trail. We went in about 4 miles. Very pleasant trail. The melt makes the waterfalls unusually spectacular.
We did hear, but not see, elk on several occasions. There were several very large, very new elk tracks on the trail. We also saw fresh bear scat on the trail at about 3 miles in.
There were a few blow-downs around 3 miles. Some of them seemed problematical getting around. One for instance required walking several crossed logs. Not that bad, though. It was much easier coming back out.
At one point near 4 miles, run off completely took over the trail. We thought we had lost the trail, but agreed, no, that small creek actually was the trail.
In all, a pleasant hike. The waterfall viewpoint (the second one from the trailhead) is definitely the better view of the falls.
