This is a 13 mile hike in the Old Faithful area. I started at the Old Faithful parking lot, and did a clockwise loop around to Mallard Lake and back down to Old Faithful. After the thermal section, most of the hike is through thick forest. I was happy to see fresh bear tracks on the trail. This hike has a very good trail all the way and was an easy hike.
Old Faithful is a cone geyser in Yellowstone National Park in Wyoming, United States. It was named in 1870 during the Washburn–Langford–Doane Expedition and was the first geyser in the park to be named. It is a highly predictable geothermal feature and has erupted every 44 minutes to two hours since 2000.
“Sunday Morning” leaves us this morning with elk bugling at Yellowstone National Park. Videographer: Doug Jensen.
Yellowstone’s autumn is defined in many ways-frost on morning grass, color creeping into shimmering aspen leaves, ice rimming mountain ponds. There are sights and smells to a Yellowstone autumn, elements that, if you’ve visited here many times, become as familiar as old friends. But nothing etches the lens through which we see fall as much as the rut of the elk, Cervus alaphus. The reason for this is almost entirely auditory.
The Sound of a Bull Elk in Autumn
If you’ve never heard the bugle of the bull elk during the fall rutting period, you are in for an experience that is at once thrilling and haunting. The sound of a bull elk bugling is something that draws many visitors to Yellowstone each autumn, for it is an experience as memorable as anything you are likely to have in the park. In most cases, the bugle starts low and throaty, rising to a high whistle, then dropping to a grunt or a series of grunts. It’s a sound that is difficult for the human alphabet to imitate, a guttural bellow, a shrill pitch, and a hollow grunting. A-a-a-a-a-a-a-a-eeeeeeeeeeeeee-oh. Ee-uh. Ee-uh. Ee-uh. It’s an odd combination that, like the buzz of your first rattlesnake, you’ll never forget.
Wyoming is a state in the Mountain West subregion of the Western United States. The 10th largest state by area, it is also the least populous and least densely populated state in the contiguous United States. Wikipedia
Precisely ageing subgiant stars gives new insight into the Milky Way’s formation, and uncovering Yellowstone’s hydrothermal plumbing system.

00:45 Accurately ageing stars reveals the Milky Way’s history
To understand when, and how, the Milky Way formed, researchers need to know when its stars were born. This week, a team of astronomers have precisely aged nearly a quarter of a million stars, revealing more about the sequence of events that took place as our galaxy formed.
Yellowstone National Park’s iconic geothermal geysers and volcanic landmarks are well studied, but very little was known about the ‘plumbing system’ that feeds these features. Now a team of researchers have mapped the underground hydrothermal system, showing the specific faults and pathways that supply the park.
We discuss some highlights from the Nature Briefing. This time, 0why an Australian university has been suspended from winning a research foundation’s fellowships, and the ongoing debate about the cause of ‘COVID toes’.

The Black Canyon of the Yellowstone covers an extensive stretch of the Yellowstone River near the northern border of Yellowstone National Park. This is a hiking and backpacking canyon, not a canyoneering destination. It’s characterized by spectacular scenery along the Yellowstone River, with interesting geology at the upstream sections.
Yellowstone National Park is a nearly 3,500-sq.-mile wilderness recreation area atop a volcanic hot spot. Mostly in Wyoming, the park spreads into parts of Montana and Idaho too. Yellowstone features dramatic canyons, alpine rivers, lush forests, hot springs and gushing geysers, including its most famous, Old Faithful. It’s also home to hundreds of animal species, including bears, wolves, bison, elk and antelope.
