8/1/19 – Thursday
This was another area that John and I had missed, largely due to crowds and no reasonable parking. This time, because again we left around 8 (more like 8:30 am) it was possible.
Norris Geyser Basin
This area is mostly full of fumeroles, where steam is venting all the time. It’s an area of high heat and low water because these steam vents are usually found on hillsides and above the basin’s water supply.
Porcelain Basin (milky color of mineral deposited here – Siliceous sinter- led to the name. It’s brought to the surface by hot water, forming a sheet over the flat surface.
Mammoth Hot Springs
The hot springs here are reshaping the mountain. As the hot water rises it goes through limestone, dissolving it only to deposit the stone as it flows above ground. Over time the water shifts where it flows, leaving chalky white terraces where before, when the water flowed, the terraces had the golden colors the bacteria would bring. As you approach the area keep your eyes peeled for Canary Terraces which I believe don’t have a boardwalk alongside. We missed them. We did manage to find a parking spot near the restrooms to get that badly needed break. Then we were able to explore the Palette Spring.
Logistically it made sense to continue on to the Lamar Valley, where the pronghorn antelope, wolves and bison hang out. We only managed to see one antelope, but didn’t get a photo, then a herd in the distance of bison.
