Yellowstone Falls is located in... wait for it... Yellowstone National Park. I bet you knew that but I just wanted to make sure. The falls consist of the upper falls and the lower falls. The more popular is the lower falls and is this weeks post picture. The lower falls is approximately 308 feet high and is best viewed, in my opinion, from Lookout Point. Yellowstone Falls is twice the height of Niagara falls although Niagara falls does have a higher volume of water flowing over it. According to the National Park Service, "The volume of water flowing over the falls can vary from 63,500 gal/sec at peak runoff to 5,000 gal/sec in the fall."
I visited the falls in early October and it was pretty amazing. I am not sure the flow rate but nonetheless by my calculations it is was a lot. There is a lookout in the park off of the north rim trail that will take you down directly over the falls. The trail is a series of switchbacks leading down to the lookout so keep that in mind. It's a strenuous but short hike and well worth it. The view you get is staring directly down a 308 foot waterfall drop. It's pretty gnarly and Highly recommended!
This weeks post image was taken with a tripod mounted 70-200. I shot an 9 image panorama. It was an overcast day which helped but I also used an 8 stop ND filter to blur the water of the falls. I shot at f8 to get the sharpest shot I could and the ND filter gave me something like a 6 second exposure. I will cover how I shoot panoramas in a future post as it's too lengthy for this one.
Yellowstone Falls is one of the most popular sights in the park and is a must see. Now only if you can keep from saying Yellowstone when you mean Yosemite or vise versa, you're better than I.
