Photos of the Week – October 10, 2019

This week, I attended the Nebraska Natural Legacy Conference, an annual gathering of conservation staff and Master Naturalist volunteers from across the state. Prior to the conference, I had time to make quick visits to a couple well-known landmarks in the Nebraska panhandle. The night before the conference, I stopped at Courthouse and Jail Rocks near Bridgeport. The next morning, I got up early enough to catch nice light at Scottsbluff National Monument near Gering. Both sites were important landmarks for travelers on the Oregon Trail but also represent significant memories from my childhood in the Nebraska panhandle.

Here are some photos from those short visits.

Courthouse and Jail Rocks near Bridgeport, Nebraska were major landmarks along the Oregon Trail. When I was in elementary school, we lived in Bridgeport and I remember visiting the site as a kid. This photo was made from 5 images merged together.

The Prairie Ecologist Goes To The Mountains

As I mentioned in my last post, Kim and I snuck away for a short vacation in the mountains last week. It was a great trip, but now I’m catching up on all the work that was waiting for me when I got home. Since I’m a little pressed for time, I figured I’d just share a bunch more vacation photos instead of writing a long pithy post on prairie ecology.

Quaking aspen at Moonshine Park, a big open clearing in the Uncompahgre National Forest near Ouray, Colorado.

When I go to the mountains, I usually try to get up above tree line as much as possible. Hiking trails that just pass through dense stands of evergreens doesn’t do much for me. I want to feel the big open space that I like so much about prairies.

However, I found this year that my objection to hiking wooded trails doesn’t apply to autumn hikes through stands of quaking aspen. WOW, that’s a great experience. Of course, I still enjoyed getting up and out of the trees too, but since we were too late for most wildflowers, the aspen provided a lot of the color in the landscape. Kim and I are already planning our return visit next fall.

I hope you enjoy these photos. I’ll try to get back to prairie photos and topics for my next post.

Autumn in the Rocky Mountains is pretty spectacular.
This was my first-ever sighting of a dusky grouse. It stepped out onto the trail in front of Kim and then let me follow it for a few minutes with my camera as it wandered through the dark understory of a dense grove of aspens and other trees.
One of the great things about hiking with Kim is that we share the same kind of curiosity about everything we see. This is a poor cell phone photo of a fly(?) larva feeding inside a gall on a Gambel oak leaf. We admired this little bugger and its two friends in the same leaf, for several minutes. It was a great excuse to stop and catch our breath while heading up a steep slope.
Speaking of curiosity, Kim and I spent a lot of time wishing we knew more about the geology of the area. The Rocky Mountains are a great place to see numerous bands of sedimentary rock uplifted through time. Along this trail, we enjoyed speculating about how these layers were laid down. The top layer shown here had lots of rounded stones (river rocks?) embedded win a rocky matrix. Directly underneath was a layer of shale or some similar flaky substance. Really interesting.
I carried a lot of camera gear up and down the mountains last week but didn’t use my macro lens much. I took this photo partly to justify the extra weight of that macro lens… I don’t know what flower it is.
The carpets of gold leaves beneath some of the bigger aspen groves on the Corbett Creek Trail were really hard to capture with photography. It was also really hard to avoid humming Wizard of Oz songs.

This mountain top near Ouray provided fall color independent of the changing leaves on lower slopes.
On Saturday, we made our way up the steep Ice Lake trail near Silverton, CO, and finally reached the lake for which the trail was named. The blue color was shocking. This photo actually UNDERSTATES how brilliantly blue the water was.
Here is ice lake from a distance, showing again how striking the color is. Apparently, the blue is accentuated by suspended particles in the water called glacial flour. The “flour” is just fine particles of rock ground up by glaciers. As glaciers melt, the water carries that dust into lakes, which (through physics I only partially understand) helps reflect light in a way that really intensifies the blue color.
The stream flowing out of Ice Lake had residue of the glacial flour on its rocks. It gave the stream a strong white color that we could see even from high above it. (I don’t know these flowers, but they were among only a few species still blooming when we were there.)
Island Lake was just a short side trip away from Ice Lake, but well worth the trouble. It wasn’t as shockingly blue as Ice Lake, but equally beautiful in its own way.
This is the view as we hiked back down from Ice Lake. The tiny lake near the center of the photo was Lower Ice Lake, which was about half way up the long hike to Ice Lake.
