From the listed put-in, boaters will likely encounter areas of swiftwater often flowing through overhanging alder. (While there are no major (or barely even significant) rapids here, high water may make passage through overhanging brush that much more problematic!) Pinnacle Falls, a big drop and portage for most sane individuals, is 2 miles into this section. While there are plenty of areas of minor rapids, there are relatively few memorable rapids, making this is a reach which is seldom boated.
It might also be noted that, while maps may show a 'Wylie Falls' about a mile upstream of our recommended put-in, all reports are that it is little more than a beaver dam and minor rapids, not worth the bother to find or boat.
