Ira Spring Trail - Mason Lake, Mount Defiance & Web Mountain via Putrid Pete's Peak — Friday, May. 31, 2024

Snoqualmie Region > Snoqualmie Pass
Route to Mt Defiance from Putrid Pete's Peak

Hard to pass up such a beautiful day, so headed out to do the Putrid Pete Peak ( P3) / Mt Defiance / Mason Lake loop, a bit of a huff, but views forever and really nice variety. 

TLDR:

  •  Snow:
    • Things changing fast, but today snow was quite manageable, not firm, and only post-holed once. I would still take spikes, even if you don't use them. Took ice axe, but did not need.
    • To P3: Snow Free
    • P3 to Mt Defiance Summit Turnoff
      • Only the odd snow patch, until...
      • Steady snow through trees from 4971' to turnoff 
      • Used spikes for the last hundred feet, but might have skipped had I known the conditions just around the 'corner'
    • Mason Lake to Mt Defiance Summit Turnoff
      • Mason lake trail area snow free, but muddy
      • Lake itself ~50% frozen, but going fast
      • Steady snow through trees 4500-5000', then...
      • Odd patches beyond to turnoff
    • Mt Defiance Summit Track
      • 50% snow, but not for much longer, snowpack very wet
  • Road: Good condition, couple minor potholes/washboards
  • Parking: 17 cars @9am sunny Friday, 20 cars @4pm
  • Flowers: Avalanche Lily's out around Mt Defiance summit
  • Note still a bit confused over which is "West Defiance"
    • This TR covers the "regular" Mount defiance.
  • People: 6 to P3, 0 to Mt Defiance, dozens at Mason Lake+
    • Everyone super friendly
    • At least 4 tents at mason lake

Putrid Peak Trail ( P3 ):

  • My shirt certainly smelled putrid after this trail
  • Peak named after Pete Schoening, a legendary Seattle climber I remember reading stories about as a kid
  • First "connector" turnoff is unmarked but obvious
  • The P3 turnoff is labeled with metal diamond blaze, and obvious
  • The trail seduces you low down with nice switchbacks
  • After the stream at ~3415 ( currently flowing ), the tone changes to up, up, up
  • At ~3800' you start to get great views
  • Although P3 is really a bump on the ridge it is a great viewpoint, and worthy goal
    • The local Marmot seemed to agree, and hung out for a while hoping for my sandwich
  • I did not do the side trip to "Web Mountain", but it looked fun
    • P.S. Is this the "West Defiance" the WTA report refers to?

P3 To Mount Defiance Summit Turnoff:

  • Sidling descent east along ridge, straightforward, though a tad loose
  • As the ridge levels out a climbers bootpath becomes apparent, which when snow free probably takes you the whole way to Defiance
  • Snow started on the ascent, but there was some human/doggo tracks to follow, and you just keep going towards the meet-up with the summer Mt. Defiance / Thompson Lake trail
  • Once joined the summer trail there was a little steep slope to traverse to get to the summit trail turnoff

Mount Defiance Summit:

  • 50% snow, but not to bad, just take care the snowpack is very wet here, and melting fast
  • Great views as always from the summit
  • Did not take the winter variant, looked pretty melted out

Mount Defiance to Mason Lake:

  • Fairly straightforward, except navigating the snow 5000-4500', with post-holing being the main worry
  • Quite a few tracks in the snow, but keep an eye on the GPS just in case
  • Mason lake area a bit muddy, but otherwise pretty snow free

All in all, an interesting route, and beautiful day to be in the hills.
