I made my first trip to SoYo in two years last weekend. Saturday afternoon we drove to the Chiquito Pass trailhead and camped. Sunday morning we hiked down to the river and followed it downstream a couple miles. Then we hiked back up to Sky Ranch Road and back to the car. 7 miles and +/- 1300 feet elevation. (Not a really hard hike but too much for me and I am still paying for it a week later) Drove down to Jones Store and then took Grizzly Road and camped. Monday we stopped along the way wherever we wanted and eventually had lunch in the North Fork coffee shop.
As far as conditions go, the weather was perfect with days in the 60's and cool nights. The mosquitos weren't bad and the wildflowers were out in force - Shooting Stars, Phlox, Dogwood, Thimbleberry, Azealia, Snow Plant, Paintbrush, Penstamen, Lupine, Pretty Face, Mariposa Lily, Leopard Lily, ............
I took a near-infrared camera which is worthless for taking flower pictures but does produce weird images. The spectrum the camera sees does not coincide with the spectrum the human eye sees. What the camera sees is literally invisible to us.
