On 4/12/19 we did Happy Dog in Halls Creek. 5 people, 1.5 hrs approach from Millers Creek camp, 6.5 hrs in canyon, 10 min. hike back. 6 rappels to 150’, mostly dry upper half, 1/2 dozen swimmers bottom 1/2, nothing in keeper mode. Water was frigid. Upper 1/2 had fairly difficult awkward stemming, bottom 1/2 has 1000’ stemming section much longer than the top but easier going. Final rappel sequence is spectacular. Poison Ivy is budding and will be thick very soon.
