This was the City Nature Challenge Day #1 and I got up at 5:30 AM to get the dogs all fed and pottied, and to get myself and Esteban ready for a day out in the field with my friend and fellow naturalist Roxanne. We went into Placer County and up along the length of Drum Powerhouse Road. My right arm still hurt from the COVID booster, all the way down to my wrist. I pretty much tried to ignore it, but sometimes I had to change which hand I held my camera/cellphone in.
On the way up into the foothills, Roxanne took a short detour to show me a spot where there were white globe lilies blooming along the road side. Such pretty things.

Next we stopped at a rest stop along the highway to use the restroom, get Esteban walked and pottied, and check out the colony of Cliff Swallows there. I could watch those little guys all day. They’re so entertaining.




Once we got going, we got confused by some of the road signs, and ended up going down a road we didn’t mean to, but at an intersection there we saw more Cliff Swallows. They were on the ground near a puddle collecting mud for their nests. We noted that the birds were flapping their wings all the while they were on the ground.




I suggested it might be to confuse and ward-off predators, but according to bird-photographer expert Ron Dudley it has a different purpose. He writes: “…It’s thought to be a defensive posture used by both sexes and meant to prevent extra-pair copulations (EPCs). At almost any opportunity males try to copulate with swallows other than their own mates and those sexually aggressive males often mistake other males for females. So swallows on the ground, both males and females, typically raise and flutter their wings in an effort to prevent those unwelcome matings while their gathering behavior makes them more vulnerable. As a result, vicious fights often break out…”
So, the wing-flapping is sort of like the swallows’ version of birth control. Hah!
The drive took us up through the foothills, past huge outcroppings of serpentinite, seeps and small waterfalls, and one spot where water (from melting snow above) was actually trickling through the rocks and mosses. It seemed that everywhere we stopped along the road, we saw a generous variety of species.





The first spot was one we’d gone to a year or so ago where we saw giant trillium, Bleeding Hearts, and Mountain Misery among other things. And we found some Trumpet Lichen among the moss on the side of a stump. We also got to see a Brown Creeper bird creeping up the side of a fir tree. It was collecting little bits of bark and needles along the way.





Further along the road we found groupings of Yellow Star Tulips and Rainbow Irises along with Goldback Fern and other plants.


In a more rocky area we found lots of lichen including Emery Rocktripe, Black Eye Lichen, and Yellow Map Lichen.



In between some of the boulders Lace Lip Ferns were peaking out. But the standout find was several flowering Mountain Jewelflower plants. I’ve been trying to find a jewelflower for almost a decade, and this was my first! I was sooooo excited! It was nice to see, too, that there were so many healthy-looking plants growing out from the rocks. Tucked in closer against the rock walls were lots of Canyon Live-Forever Dudleya, most of them in bloom, too.





On the opposite side of the road was a steep drop-off covered in trees. We could hear a loud bird singing from the top of a tree nearby. I caught a glimpse of it, and could see it was a male Black-Headed Grosbeak, but it flew into another tree before I could get a photo of it. Luckily, it didn’t go too far, and we were able to take some photos and a video snippet of it before it flew off.
In other areas we found end-of-the-season larkspur, some Pacific Hounds Tongue (“Dog Lick”), and flowering Broad-leaved Stonecrop.





We also found that several of the Dogwood trees were in bloom. Sooooo lovely. All the “green”, cool temperatures and fresh air was just what I’ve been needing. We were also pleased to see the huge outcroppings of serpentinite along the road: shiny, slick, almost glassy, in varying shades of green.

According to KQED: “…Serpentinite is a metamorphosed version of rocks that make up oceanic crust after they are incorporated into subduction zones (plate boundaries where oceanic plates are thrust under continental plates). The recognition and study of serpentinite in California contributed to the understanding of modern plate tectonic theory… Serpentinite has a unique association with California for many reasons including: its association with gold deposits and the resulting California Gold Rush history, many plants unique to California grow on serpentinite-rich soils, the fact that serpentinite is thought to promote slow (and less hazardous) ‘creep’ along faults, and others…”
In 2009, there was a bill introduced in the state Senate to remove serpentinite as California’s state rock. The bill suggested that serpentinite shouldn’t be the state rock because “serpentine contains the deadly mineral ‘chrysotile asbestos, a known carcinogen, exposure to which increases the risk of cancer mesothelioma.”
The fact that there is no such thing as the mineral chrysotile asbestos was ignored in the bill. According to KQED: “…There is a mineral ‘chrysotile’ that crystallizes into a fibrous material referred to as asbestos but not all varieties of serpentinite contain it…” The only real danger from the stone was if someone threw a chunk of serpentinite at you and it struck you in the head. So, the bill failed – as it should have.
We drove past the plot of ground, a shallow meadow, that is regularly used as a makeshift shooting range by locals. It’s so sad to see all of this destruction in the middle of such a lovely environment. The ground is literally covered in shot gun shells, shot up boxes and other trash. There are circles cut into the ground by morons doing “donuts” with their vehicles, and rocks painted with lurid green smiley faces and graffiti. It’s all just sickening to look at.

We were hoping to get to see the powerplant at the end of the road but access was blocked by a gate that, although it was open, was covered in “no trespassing” and other warning signs. The powerhouse, a hydroelectric plant run by PG&E, is over 100 years old. It’s adjacent to the New Drum Afterbay dam which is over a mile long. There is so little information available about the dam and the powerhouse that it makes me a bit suspicious about it. Like, what’s really going on beyond that closed gate? Hah!
For me, it was extra fun to also be able to find several galls on the canyon live oak trees including Clustered Blister Galls, Fluted Gall, Gouty Stem Galls, and Hair Capsule Gall.
