Trip Itinerary:

Day 1 Mowich Lake TH to Seattle Park.  We take the Eagle's Roost/Spray Falls trail up to the meadows then take a social trail up to lake below the foot of the Flett Glacier.  We will then proceed off trail further up the hill until will intersect the boot path up to Observation and Echo Rocks (we won't be scrambling the rocks).  We then will proceed down the boot path to the main trail that connects Spray Park and Seattle Park and head East, soon leave this trail and find a campsite by one the lakes, tarns in Seattle Park--7.8 Miles, 3000' gain.  If time and interest allow we will do an option exploration to the lateral moraine of the Carbon Glacier and gawk at its grandeur. 

Day 2 Seattle Park to lake East of Mother Mountain.  We will pack-up and leave Seattle Park, regain the main trail and shortly thereafter, stash our packs and don small summit bags and proceed off trail into amazing Mist Park, exploring in a broad loop. Returning to our packs we will proceed on the main trai, taking the right wye toward Knapsack Pass.  We will again drop our packs and with our summit bags take the boot path to the top of Mount Pleasant and Hessong  Rock. Returning to our packs we will continue on the boot path toward Knapsack Pass, turning off trail, going East and find a camp near the two larger lakes at elev. 5500'--7.7 miles, 3000' gain.  Extra exploring in the evening if desired.

Day 3  Day hike, off-trail with summit bag through a gap (small pass) to Doe Lake (elev. 5100') due North of First Mother Mountain.  Return to camp and pack-up.  Proceed up to Knapsack Pass and drop packs again and take the boot path up to First Mother Mountain, or at least as far as it is safe to travel for participants skills/experience level. Return to Knapsack Pass, and go down to the Mowich Lake TH--4.7 miles, 3200' gain.


There are no designated campsites for this trip, we are only assigned to general areas where we will need to find adequate spots for our tents.  While the settings are stellar there is no guarantee that your particular tent spot will be as grand or flat. This will be an amazing trip, however due to its complexity and challenges Leader's Permission is required.   Participants needs to explain to the leader the following:

1) Your backpacking experience during  the current season that demonstrates your conditioning to do this trip successfully.

2) Your experience with off-trail travel that adequately demonstrates this skill.

3) Your attestation that you are fully vaccinated for Covid-19.

Please No Leader's Permission until Monday July 19th, 8AM

There was a $26 fee for reserving these campsite that will be divided among the group.  It is going to be good.  Rob
