A lot's been written about these trails in recent WTA reports, so I won't bother with too many details (see other reports).
An early start put me on the trail at 5:45 Friday morning. It'd been cloudy and somewhat overcast in the Sound for a few days, but I thought I'd take a chance... My karma must be high, because while I started the day with clouds and some light fog, it began to break up around the time I hit Lower Morovitz meadows. Nice views out over fog shrouded valleys, with the sun still low. Went up to check out the Park Butte area first (did the loop clockwise--more later) and saw a few groups just waking up. Had the lookout to myself--unlocked, but unmanned--and by this point, nothing above me but blue sky, with some cottony clouds still present down in the distant valleys. Spectacular. Spooked an owl from the scrubby firs just below the lookout, but wasn't fast enough on the draw for a pic. Only wildlife I saw the entire day, excepting the ubiquitous marmots.
Descended back to Cathedral Pass, and started up Railraod Grade next. This is a nice trail along the crest of a lateral moraine formed by the Easton Glacier. Geology in the raw! Folks were just waking up in the camps along the trail, and I met a few climbers just descending from Baker. Kept heading up-and-up until the trail peters out somewhere above 7000' (you can reach well above High Camp this year...) Considered heading over to have a look at Deming, but knew I had the bulk of Scott Paul for my ""return trip"" so I decided to leave something for another time...
Descended back down to Lower Morovitz to meet up with the Scott Paul trail. The SP is visible from the lower slopes of Railroad grade, making its way up the opposite (eastern) moraine on the other side of the upper reaches of Rocky Creek. You can see the Creek crossing (a small suspension bridge) from up here too, and when I was heaidng back down, saw someone taking the shortcut down the side of the moraine, instead of backtracking (in mileage and elevation) back to Lower Morovitz. I backtracked--getting there is part of the fun!
THe westernmost fork of Rocky Creek is bridged with a nice suspension bridge, but no bridge across either the eastern fork of Rocky or over Sulphur Ck on the Scott Paul. No worries though--there were plenty of rocks and shallows to get across. I did see some folks with kids and some with a dog having difficulties at these crossings though. Looped back to the car clockwise on the Scott Paul, and found it a nicely-maintained and scenic trail (hadn't been on this part before). The northerly part rounds ridge after ridge into meadow after meadow. The flowers are well past peak, but should be gorgeous earlier in the year. The final 3 miles are all on the downhill, through nice lush forest--a nice grade for descending here, and mostly a nice soft forest tail--easy on the knees.
This was a pretty decent dayhike. If you have the time, I'd recommend doing all the above as an overnighter, camping at one of the many sites near Cathedral Pass.
Advantages of a clockwise loop: check out the Pk Butte lookout before the throngs get there; hit some of the higher country (like RR grade) before the sun gets too overwhelming; the best views of Baker on the Scott Paul; and a nice descent for the last 3 miles.
Advantage to a CCW loop: I bet the view from the Pk Butte Lookout would be awesome at sunset, then it's a quick descent.
