Made my 5th highpoint on the summer solstice with my lil sis. No snake sightings on this day!!!
Living half the country away, it's difficult to pinpoint weather conditions in advance; you hope for the best, and work with the conditions as best you can. My wife accompanied me to White Butte a couple hours before sunset, but unfortunately there was a major storm which hit that morning and another major one approaching while we were there (so we had little time to "hang out"). The ground and slopes were slick!!! We were covered in that milky gray-white mud, which is like cement, and we could have glissaded down the slippery slopes if we wanted to. No rattlesnakes, but TONS of pheasants, rabbits, quails, and field mice... and even one badger (which was pretty cool to see).
