Placer Big Trees Grove

As if there aren't wonders enough in Placer County, we even have our own grove of Giant Sequoia trees. This northernmost grove was discovered by a prospector in 1855. Six Giant Sequoias are standing. One is named after a state senator from Placer County (Lardner). Three are named after Allied commanders from the Great War (Haig, Joffre, and Pershing). Two remain unnamed. While the Joffre Tree is the tallest (250 ft), the Pershing Tree (225 ft) is the largest by volume, its trunk 12 feet in diameter at breast height. These Giant Sequoia are small compared to their southern cousins.

I visited the grove on June 4th. It had been many years since my last visit.

In Foresthill I stopped by Worton's Market to consult the map, and to take in the wonder of the vast canyon of the Middle Fork American River. Nearby were about a half-dozen Forest Service workers who had stopped for supplies. With their trucks and trailers and all terrain vehicles, plus their shovels and ropes and assorted other gear, they were clearly heading out to the wilderness for some hard work. They were in their late twenties and early thirties, all men except for the one woman. From my queries I learned their job was to seal the entrances of abandoned mines. What a dream job to have.

A short distance beyond, I turned onto Mosquito Ridge Road, which follows the Middle Fork. I stopped in places to examine walls of slate twisted in crazy angles from subduction. Long ago there had been a mile or two of slate above these points, but those rocks eroded away and now fill the level Sacramento Valley.

I crossed the bridge over the North Fork of the Middle Fork of the American River. With easy access to the river, many people try their hand at finding gold around here. I've worked gravels upriver myself, but found little color. At the side of the road was a pile of camping and prospecting gear. I stopped and got out and looked out from atop the bridge. I saw the owners of the gear off in the distance, carrying more items up trail. I wondered how their luck went finding gold.

I continued up Mosquito Ridge Road. The views of the canyon were magnificent, but I had to pay attention to the road to keep from driving off it.

I left warm and sunny conditions in the Valley. The weather can change quickly in the mountains. Around Milepost 23 (I think at 4500 feet) the temperature had cooled by some fifteen degrees, and there was briefly a light rain.

I took the turnoff to the Placer Big Trees Grove, and soon reached the parking lot. Only one other vehicle was there, and the occupants (two young men with two dogs) were departing the trailhead as I got out of my truck. So with them a good way ahead of me, I essentially was alone on this half-mile trail. I took an interpretive booklet and commenced my walk. The cloud cover gave good diffused light for photography.

This grove is so far from the others that there has been no cross-pollination from outside Giant Sequoias, leading scientists to wonder if these trees have evolved their own genetic code. In the past century, Giant Sequoia plantations have been established around this area. Potentially in a thousand years Giant Sequoias will tower here and there. But the plantation trees may impact the genetics of the descendants of these old timers, and nobody knows if this is a good thing or not.

This is a grove. One can find individual trees. I once saw a lone Giant Sequoia by a remote trail, near Dix Mine in Placer County.

On the return drive I had this view of the canyon. Magnificent.

And one more picture of those twisted slates.
