I got up around 5:30 this morning, so I could head out with my friend and fellow naturalist Roxanne to go into the South Yuba River State Park in the Penn Valley area of Nevada County. We were interested in hiking the Buttermilk Bend Trail. It was partly cloudy, slightly breezy and cool all day. A lovely day for a nature walk.



It took about 2 hours to get to the park, including stops for gas, coffee and a potty break. We got there via highways 70, 49 and 20 to Pleasant Valley Road. For the most part, there was a lot to see on the drive, especially as we got closer to the park. Some of the roadside embankments were covered in white Globe Lilies, irises, yellow Pretty Face, blue Ithuriel’s Spears, and French broom. Pretty!

We went past the historic barn and the covered bridge(which is undergoing a complete overhaul), and pulled into the main parking lot near the head of the trail. We attacked the trail from near the kiosk and had to climb a steep incline to get to the trail itself. Next time, we’ll enter the trail from the end of the parking lot where there’s a shallower incline and several small bridges that lead up onto the trail. After that initial incline, the rest of the trail was VERY easy to walk, and provided beautiful views of flowers, the river, and acres of a wide variety of trees.



All the while we were walking, we were lulled by the sounds of the river.
Between the views, the research we were able to do, the company, and the weather, it was a great hike.

We could smell and see smoke in some spots on the other side of the river, and figured that they were controlled burns. Cal Fire was out there — and that turned out to be a good thing for me. I’ll tell you more about that later.
Controlled burns could be seen throughout the forest
There were several different kinds of oak trees in the area: coast live, interior live, blue, valley and black oaks. So, we got to see quite a few galls including some folded leaf galls, some old Gray Mid-Rib Galls, Round Leaf Galls, spring generation galls of the Live Oak Gall Wasp (that look like funnels with a cap on them), and lots of spring generation galls of the Two-Horned Gall Wasp (that look like shiny brown beaks).
We were surprised to find galls on some of the wild lupine, and some examples of “witches’ broom” on a toyon bush. The broom is caused by a fungus that creates “…an abnormal brush-like cluster of dwarfed weak shoots arising at or near the same point…” Very cool-looking. I’d seen photos of them, but had never seen a live one before.






Also on toyon, was found some wrinkled leaf effects created by woolly aphids. There was one leaf that was so full of the little guys that the honeydew they produced literally poured out onto our hands making everything sticky.
We got to see quite a few butterflies including Pipevine Swallowtails, a Tiger Swallowtail, several beautiful Checkerspots, and some Cabbage Whites. We also saw some species of Blood Bees, mason bees, a camel cricket, and caterpillars.





As I mentioned before, the flowers were just lovely. We saw one of my favorites: the Twining Snake Lily. They have a spray of dark pink florets at the end of a long stem that twines its way through the trees, bushes and undergrowth to find the sunlight. One of them was growing over our head and came down from the side of the hill and into the tree branches above us.

New-to-me flowers included the White Globe Lilies, Linear-Lobed Owl’s-Clover, Blue Head Gilia and Ookow. The Ookow were so intensely purple-blue they really stood out.




We saw a couple of squirrels and could hear a few different species of birds, including Lesser Goldfinches. They were eating the seeds and tufts from the plants along the trail.
On some of the rocks along the trail, we came across a handful of Western Fence Lizards (the “blue belly” lizard that do push-ups), including one that had splayed itself over the warm surface of the rock, stretching its legs out in all directions so it could flatten its belly on the stone. On another rock, we found a VERY pregnant female. She had to lift herself up on her front legs to keep her belly from dragging on the ground. Poor baby.

We walked for a little over four hours, which is usually past my strength and pain threshold, but we were seeing so many thing, and the weather was so beautiful, I didn’t stop when I should have. Just as we got close to the parking lot, I “hit the wall”. I was dizzy, suddenly completely exhausted, and couldn’t walk. Even the feel of the camera and my carry bag around my neck and shoulders was too much. I found a fence post and leaned over it for support while Roxanne went to get the car and bring it closer to me.
As fate would have it, that was the same time the firefighters were returning to their vehicles after working on the controlled burns. I wasn’t going to bother them, but as the seconds went by, I was feeling worse and worse, so I called out with a very weak voice. Thankfully, some of them heard me and two came right over to see if I was okay. Those two firefighters ushered me back to the car while another one ran to get me a bottle of water.

I felt I was hydrated well enough, but I hadn’t stopped anywhere along the four hours to get something to eat, so I think my glucose levels had just crashed. The firefighters made sure I was safe in the car with Rox and hung around until I ate something. A few minutes later, after some rest and something to eat I was fine. [[THANK YOU to Rox, the Universe, and the guys from Cal Fire @CALFIRENEU]]
It was a long day, but one of my favorite outings in a long time. I was so happy we were told about this trail.
