This is a covered walkway that connects the bridge from the previous two photos with the main entrance of Bielefeld University, Germany. It's quite foggy so a lot of light is scattered before falling through the glass roofing from all angles. They have kind of an algae problem with this roof, also speaking to the quite humid climate Bielefeld is renowned for. Let's just hope the lunatics in the US Congress withstand reason long enough for things to just get a tiny bit more arid around here.
Pentax PC35AF, Kentmere 100 @ 100
Los Angeles County, California, March 2022
Found while exploring some new curvy roads. Negative is a dusty, scratchy mess, but I love this sign. First roll with my newly-acquired PC35AF. Had one as a kid, kept it with me all through college, and this one is once again my constant companion. What a delightful little camera. Never did find any algae, though.

The substance on the trunks and branches of these trees is called "Trentepohlia". It is a genus of filamentous green chlorophyte algae that lives on tree trunks and wet logs. The strong brownish-orange color of the filaments, which mask the green of the chlorophyll, is caused by the presence of large quantities of carotenoid pigments. I found trees covered with this growth on the top of a high bluff overlooking the Pacific Ocean near Half Moon Bay in northern California.

Freshwater diatoms, an algae, surrounded by some lime scale on aquarium glass.
Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons (e.g. Fragillaria), fans (e.g. Meridion), zigzags (e.g. Tabellaria), or stellate colonies (e.g. Asterionella). Diatoms are producers within the food chain. A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica (hydrated silicon dioxide) called a frustule. These frustules show a wide diversity in form, but usually consist of two asymmetrical sides with a split between them, hence the group name. Fossil evidence suggests that they originated during, or before, the early Jurassic Period. Diatom communities are a popular tool for monitoring environmental conditions, past and present, and are commonly used in studies of water quality.

The third of our four full days in Yellowstone, and as odd as it may seem, the thrall of the geothermal sites was beginning to pale. Its not the sites themselves, but the queues to get into the parking areas and then the number of people at the well known sites.
Black Sand Basin is beside the Upper basin where Old Faithful can be found, and has two small geysers erupting almost continuously.
I loved the contrast between the rocky sediments and algae growth and the green and blue of the trees and skies.
IN the middle of a meadow, there would be a pool, and from it steam where boiling water, of the deepest blue, was percolating up.
Geology in action. Again.

August 16
We were awake again at half five, if not an hour and a half before. Again. But outside the day was dawning clear and bright, and the moon was just visible in the lightening sky,
We were ready to go out by half six, and with the plan to go to the south east corner of the park to see more geothermal action. Sun was coming up on the way to Tower, and mist rose in every river valley, over every lake and pool. I could have stopped and took shots, but would not have done it all justice, so take my word. Glorious.
We take the road up and over the middle of the park to Canyon village, where at the gas station I buy coffee and cookies, so we could eat and sip on the winding and misty road towards Old Faithful. We stop a couple of times at some fumaroles, and all we could see was so much steam, but the vents gave out the noise of an express steam locomotive.
And despite being only seven, a few people were about. But by the time we got to the Middle Basin, there were just a few parking spaces left, one of which we bagged, and set off over the bridge and along the boardwalk to the many fools and terraces that steamed in the cool morning temperatures, and reeked of sulphur.
Pools of all shapes, colours and sizes, reflecting the now clear skies and wooded hillsides. I marveled again at the patterns and colours of the thermophiles that live in these conditions, and take their photograph.
Strained parents tried to inform and educate their children, and I said to one how great he took the time to read each information board to his uninterested two daughters, and told him, one day they would appreciate the effort.
We drive past Old Faithful and its crowds, although to be honest traffic was so light, it wasn’t a problem. We stop off at a smaller geothermal site, more pools, fumaroles and small geysers. Amazing really, and a river meandering through the activity, and water from the geysers and pools drain into the river. All around all sites is Bison poo, as I think the animals go there in the depth of winter where the heat stops the worst of frost making eating easier.
And we are done there too, so take the Grand Loop road south and then eat towards Yellowstone Lake, where we hoped it might be quieter and we could get some food which was not burgers.
I am sidetracked by the discovery beside the road of a small lake covered in water lilies, and the air filled with dragonflies and butterflies. We spend a fine half an hour here, chasing both, and me getting more shots of American Painted Ladies and a Green Comma.
We drive along the shore of the lake, and I spy a small island with a single tree on it, so think of a friend of mine in New zealand who has a lake nearby to where he lives which as a tree growing out of the water near the shore. Anyway, I think this island and tree deserve a photograph, so snap it.
We find the lodge, not that it was lost, but it is being renovated, so we nearly didn’t try to go in. A good job we did as the wooden building was fabulous, and the cafeteria was open, and served other things, so had a bowl of chili and a salad, jools had chicken pie and salad, and the dining room, which must have sat 500 at least, was nearly empty. We have a seat by the window, looking out onto the lake.
On the way back take the road to the east gate to see what the scenery was like; mostly a dead forest caused by some fire in the recent past, thousand upon thousand of dead tree trunks covering hillside after hillside, thankfully it was sunny or it would have looked spooky.
We turn for home, as thunderclouds form overhead and we could hear the distant rumble of thunder.
We do stop at one final geothermal site, a mud volcano, which, if I’m honest did disappoint, most being lost on clouds of steam, but the bubbling was more of muddy water than say, mud.
At the top of the pass back towards Tower, we stop twice to look for wild flowers and more butterflies, as I bought a book on both at the lodge, so now can identify what we see, sometimes.
The pass was in bright sunshine, yet to the north the sky was black with stormclouds and the wind picked up. On the drive back, it did rain, but not too hard and by the time we got back to the cabin, the sun had come back out and the ground was drying.
We go back to the falls after a cup of coffee, as I wanted to take detailed shots of the coloured terracing, there were still many people about, but not too crowded, but I do smirk at the trend of people wanting to be taken into front of something, as if that is the only proof they were here. As if it matters, so I watch French families and Indian families take selfies and shots of each other, then get the shots I wanted, then wait for Jools to take her shots.
We have chicken wraps on the stoop for supper, along with bottles of Moose Drool, which was pretty darn good way to end the day…..

I am told it tastes like carrots!
The second cascade of the Diwan Tembun water fall is a spectacular drop of sixty feet, which gurgles into the narrow gorge. The green moss & algae covered rocks on the mouth of the waterfall is a slippery edge to tread on, but provides such a spectacular view, that I wouldn't be the only crazy photog to hang on the ledge for one killer, literally killer image. :-)
Algae has so many Leaves! I know it does, but this was the first time I noticed in detail.
