I went as far as Mazama Park. Many blow downs over trail first two miles, few after. Many obsticals, includding washouts, trees, logs, etc. NO major slides though. Very time consuming if backpacking.
Day hikers a little easier, but plenty of bivouc.
Some wildflowers blooming, few wild Orchids, some Brain Mushrooms. To Mazama park you can travel through a lot of old growth forest, very beautiful. At Mazama park area, you encounter the beginnings of snow fields. I only round triped it to Mazama Park, took about four hours with very few stops. Faster coming down than going up but many slippry roots and loose debris on trail, so caution is advised on the travel back to trailhead too.
