South Fork Tr946 leads to Ravens Roost and a somewhat technical Middle Fork Little Naches River Tr945 descent, at the edge of the Norse Peak Wilderness.
South Fork Tr946 and Middle Fork Tr945 are connected by a portion of FR1902 and Pyramid Peak Tr941, near the Bear Creek Tr943 to Mount Clifty Tr947 loop ride.
Ding: If the 2.5mi of 12% ascent seems like too much (and would be for most intermediate riders), then use Sand Creek Tr963 and 6.3mi of the 7.5% grade FR1902 for the Raven Roost ascent.
The most interesting downhill is in the first 1.5mi on Middle Fork Tr945, a 1700' descent, or 20% grade.
The steep downhill comes at the usual cost, which is the long climb to get to the top, although shuttling FR1902 is certainly an option.
Like all other steep Cascade Range descents, every degree of downhill grade greater than 10% multiplies the miles of climbing.
With a typical sustained climbing ability of 7%-10% for most riders, getting to the top of a 1mi, 20% grade downhill takes about 3mi of climbing.
In this case the ratio is 4.6mi of South Fork Tr946 ascent (4200'-5900') for the 1.5mi Middle Fork Tr945 descent back to 4200'.
A good example of this rule is Pot Peak Tr1266, which pays off in a long enough descent to make all that climbing worth it.
Like most of the other advanced rides in the Cascade Range, it pays to find terrain which suits the riders preferences and skill level.
Norse Peak Wilderness Hiking: The Area map shows a couple of hiking options from the Ravens Roost comm site, using Pacific Crest Tr2000-I to connect Raven Roost Tr951 and Louisiana Saddle Tr945A, or for a shorter, easier hike, shuttle from Raven Roost to SR410 and descend Cougar Valley Tr951A to Crow Lake Way Tr953. Crow Lake Way Tr953 ties into Pleasant Valley Loop Tr999 near the SR410 Pleasant Valley CG.
The Greenwater Lakes hiking trails are shown on the Noble Knob Tr1184 page.
