Quartz and gold Quartz and gold are very different minerals. One is an oxide, one is a metal. One is only a single element, the other is a compound of two different elements. One has a high hardness and is tough to scratch, the other is soft and easily scratched. However, these two distinct minerals are found here together for a very important chemical reason.

Video by Ronan Donovan @ronan_donovan | This is Bearzilla. Estimated to weigh in the 600-700 lb range, this is a really big male for the Rocky Mountains. What's interesting is that most bears in March emerge from hibernation lean and muscular, having burned through their fat stores. But not Bearzilla. I spent a few weeks watching him gorging on several bison carcasses along the Yellowstone River in March. Of the six other male grizzlies coming by to feed, Bearzilla was by far the largest and most rotund. He was also the only bear that was relaxed enough to nap and play near the carcasses. The rest of the bears ate fast and got outta there quickly. In this video, Bearzilla gets annoyed with the ravens, swats a European starling, and plays with his meal. It's a brief window into the day in the life of a Yellowstone grizzly. Video taken while on assignment for @natgeo Hope over to @ronan_donovan for more photos and videos of Bearzilla

NATURE IN MOTION - Specifically, the perpetual motion one sees in Yellowstone National Park. Highlights from my October visit include Snowy, a three-year old grizzly bear, thermal springs, tumbling waterfalls, and of course, pondering bisons basking in a dust bath.

  • Video by @renan_ozturk // A serendipitous close encounter with a heard of buffalo on Pine Ridge Indian Reservation while shooting for @gatherfilm feature doc on Native American food sovereignty ~ More knowledge from director @mrsanjayr - The Oglala Lakota Native Americans on Pine Ridge are as resilient and proud as they come. Much is made in the Western press of the alarming poverty on the Reservation but in my opinion much context is missing. These great Peoples bore the brunt of the US military’s rage post Civil War. In fact the military enough was not sufficient to force their surrender. US government policy shifted to adopt asymmetrical warfare - destroying the food supply of the Oglala Lakota became the key to weakening the core of their identity. “Kill one buffalo, kill two Indians”, a quote attributed to a Colonel Dodge, was more impactful than bullets. The buffalo population was reduced from 60 million to just 24 individuals. Yet the ancestors of the present day Natives did not give up and as a result, the Buffalo people, as they’re known, are experiencing a slow but marked rejuvenation. Folks like Ed Iron Cloud, who considers himself a “caretaker” of the buffalo rather than a rancher, continue to grow the strength and numbers of these once mighty herds. The Buffalo People are on the ascendant.
