thanks for the positive comments guys, as more adventures unfold I'll try to post them up.
And Mike, I just looked up the Agartha route in the Blue Lines book and I can't tell based upon the description. There was a massive wet gully to our right that I would expect to ice up in the winter. but I doubt I have it in me to hike out there this winter to look....
And I've been thinking about silver lake for sometime now. Hopefully this fall we'll be doing lots of exploring out there...
