    Up at 6am.<\/strong><\/p>\n

    Walking by 8:30am.<\/strong><\/p>\n

    The crew was all fast \u2013 except for me\u2026<\/strong><\/p>\n

    I dragged behind on the trail and they bounded ahead.<\/strong><\/p>\n

    I was tired from the Lamarck mission the previous day but that mattered not \u2013 these folks are always faster than me.<\/strong><\/p>\n

    I caught up when they took breaks then from Lower Lamarck Lake, we rolled together.<\/strong><\/p>\n

    The terrain is challenging and gorgeous in here.<\/strong><\/p>\n

    We hit snow after about 2 hours of walking and did a small bit of skinning to the base of the chute.<\/strong><\/p>\n

    From there they put in the booter and I followed.<\/strong><\/p>\n

    We topped out 3 hours and 47 minutes after leaving the car.<\/strong><\/p>\n

    The views of Lamarck proper were impressive.<\/strong><\/p>\n

    We enjoyed the top and dropped in when ready as we watched the clouds building.<\/strong><\/p>\n

    The skiing was good and dogger approved.<\/strong><\/p>\n

    Beautiful, textured corn with some big smooth patches on the left.<\/strong><\/p>\n

    It skied like a dream and we all met up at the bottom.<\/strong><\/p>\n

    From there it\u2019s a complex ski\/traverse back to the shoes then a jolly old walk back to the car.<\/strong><\/p>\n

    We hit the car 6 hours and 57 minutes after leaving it.<\/strong><\/p>\n

    Feet went directly into the ice-cold stream and it felt oh so good.<\/strong><\/p>\n

    Directly to Bishop for a quick jamboree of BBQ and ice cream.<\/strong><\/p>\n

    Holy Smoke Texas Style BBQ delivered (I went for the Redneck Taco) and the Salt & Shop ice cream was on another level this day.<\/strong><\/p>\n

    When we asked if there was ice cream, she said no, there was only vanilla ice cream, and then we found out there was also a toffee peanut butter brownie.<\/strong><\/p>\n

    We combined those two and went straight to heaven.<\/strong><\/p>\n

    Fox was loving it.<\/strong><\/p>\n

    We grabbed cheap Indian gas and headed back up the hill to our gracious abode in Mammoth, satisfied and buzzing from the day.<\/strong><\/p>\n

    Thanks, California!<\/strong><\/p>\n
