We hiked steeply down from Geneva Lake into the North Fork Valley.  From there we climbed steeply through the woods to the Hasley Basin, which was open country, full of wildflowers. Because it was warm, we stopped and rested under a small grove of trees for a couple of hours, eating, resting and treating water from the stream.  We then climbed over an unnamed pass and high into the East Fork Basin where we crossed the basin to undertake the steep four hundred foot climb to the top of Frigid Air Basin.  The weather was clear and we camped on top of the one hundred foot wide, grassy ridge at an elevation above 12,600 feet.  The ridge dropped off steeply on both sides to a landscape of sweeping, green curves.  Directly across the basin to the east was dramatic Maroon Peak with its layered form. Late in the evening, the full moon rose above the endless vistas.
