MMM Ridge

An easy to moderate scramble of 6 miles and 3,000 feet of elevation gain. A short rock scramble at the top gives good views of Mount Teneriffe and Green Mountain to the west, Mailbox Peak to the north and Snoqualmie Pass to the east.

getting there

Take Exit 38 off of I-90 and park in the climbers parking area at Change Creek (1,210 ft).

approach & ascent

Follow the prominent climbers trail up the west side of Change Creek to the Deception Crags climbing crag on the Iron Horse Trail. Travel east on the Palouse to Cascades State Park Trail (formerly Iron Horse/John Wayne Trail) less than 200 yards and there will be an unmarked trail to the right of trestle fencing heading up the hill. The rough trail begins between the trestle bridges that span Change Creek and Hall Creek. It is pretty hidden so start looking for it as soon as you cross the bridge. A few feet up the trail a sign reading “Change Creek Trail” will confirm you’re on the right trail.

There is a trail to the right at ~2,390 ft that leads to an overlook with a view comparable to Dirty Harry's balcony. A prominent prow rock marks the turn. Main trail goes left of the prow and the easy to miss trail that heads back on the right goes to the overlook.  The MMM Ridge route has very little scrambling over all and adding the side trail makes it much more challenging. It gives you the first scrambling of the day and also very imposing exposure. About 100 feet past the overlook side trail there is a sign for "Change Creek Vista."  A few hundred feet past this sign is the turn off to Hall Point, another optional side trip that leads to a balcony overlook (think Dirty Harry's without the crowds).  This is roughly the half way point.

At the Hall Point junction, go right towards Mount Washington. Travel 0.25 mile and there will be a side trail heading back on the left. Look for the sign that says "J's Landing," an open area that looks a bit like a rock quarry with moderately good views. Just past here look for the "MMM Ridge Trail" sign and follow it. The trail will turn into a very old logging road, and shortly after that you will see "the pyramid" a little down to the left (southeast). The trail/road switches back up and behind where you will obtain the ridge. The scrambling starts here. Pay attention on the way up as there are a couple of spots where it is easy to miss your down route on the way back. Most of the scrambling is short easy rock, but there is one challenging rock traverse. Keep following the ridge up until you get to the obvious summit (4,240 ft) at the top of a grassy slope.


  • There is not much scrambling , but this is a great beginning rock scramble.
  • It is a better, much less crowded conditioner than Tiger Mountain.
  • The views better than from Dirty Harry's balcony.
  • It's a good after hours scramble near Seattle.
