Big Surprises at Fish Creek Valley

I’d been looking forward to going to the Rogue-Umpqua Divide all year, but I just couldn’t seem to squeeze a camping trip down there into my schedule earlier in the summer. Then, in late July, the Whiskey Complex fire erupted east of Tiller, just 9 miles west of Donegan Prairie, one of my planned destinations. So much for that. But last week I was lying awake in the middle of the night, my mind wandering all over the place as it often does in the wee hours, and I thought, to hell with worrying about the smoke, I’ll just go to the north end of the Rogue-Umpqua Divide. Fish Creek Valley is one of my favorite places, and there are lots of late-blooming flowers to make a trip in August worthwhile. Unlike many ideas born in the middle of the night, this one still seemed realistic in the morning, so a couple of days later, I packed up my van and headed south.

Rattlesnake Mountain looms right above Fish Creek Valley. The smoke in the air makes it seem much farther away.

Cirsium scariosum on Rattlesnake Mountain

Cirsium scariosum

Elk thistle (Cirsium scariosum) with a view of the Crater Lake Rim. This appears to be the only population on the west side of the Cascades.

I went back to Rattlesnake Mountain several days ago. I was too early for the bright yellow Orobanche, but I found a single O. fasciculata a few inches from Eriophyllum lanatum. I had no luck relocating that little Draba that might have been lonchocarpa, but I did hit it perfectly for the elk thistle (Cirsium scariosum). I was quite surprised to find 2 blooming plants right on the summit. There certainly were no blooming plants up there in the past, although I might have missed seedlings. I did what I had contemplated for a while and climbed down the rocky south-facing side. It was relatively easy (and safe) along the step-like south ridge. The west side is sheer cliffs. I passed a budding Orobanche pinorum right near an old dead stalk in the same spot I saw one on my last trip in 2007. The Hieracium greenei was also in bud. There are several old whitebark pines on the top, one with some cones (Rattlesnake Mtn is one of the highest points in the Western Cascades). Farther down, I was happy to see what looked like young trees, with no old dead branches.

As you go down the slope, it becomes more gravelly and almost plateaus before another cliff. This is where I have to go down the east slope to reconnect with the trail. That’s where the Cirsium scariosum I’d seen in the past was. I looked all around this area and found 4 large blooming plants and approximately 50 young plants. I was guessing they were monocarpic because there were no small blooming plants and I found one dead one with dried flower heads and tiny seedlings next to it. I just confirmed that on the FNA website. I couldn’t bear to harm the beautiful blooming plants, but I did press one youngster for the Herbarium. I hope it is useful. The population seems quite healthy. I wonder if it is expanding, or I just didn’t look hard enough on my other trip to this spot. I will have to check it again in a few years and see how it has changed.
