It's one of the most popular sights in South Dakota. More than 1,000 buffalo rounded up through the Hills of Custer State Park.
Coming in from the West, East and South of Custer State Park this year, herds of American Bison, pushing their hooves through the South Dakota grasslands.
Mark Hendrix, Resource Program Manager says, "It was actually a little more work this year just because we had to bring the herd together out there just on the backside of that Hill from the solar well that we have out there so then bringing them all together and then making it for the last push."
More than 20,000 people made their way to the park
to see 20 selected cowboys and cowgirls lead the way and catch the herds collide.
Betsy Mardanay of Madison, WI says, "It's just like very American, the middle of the country, something that you can't see all over."
After, spectators took a trip to the corral to witness even more.Through a calf system and an adult system. The animals are sorted, vaccinated, branded and checked for health purposes to figure out which will be auctioned off next week, while others will be sent back into the arms of nature.
Matt Snyder, Park Superintendent, says " We basically have an overbearing carrying capacity of 950 and we're slowly getting back up to that after several years of drought. We've had some good moisture the last couple of years so we're slowly rebuilding that. That's why you're only going to see about 250 animals auctioned off this year because we're slowly building."
Most people say for them, seeing the way the creatures move was mind blowing.
Kathryn Mauck says, "It was awesome. It was cool to see the crowd and it's definitely a different culture than we're used to so it was fun."
Phil Ost says, "I think seeing that many buffalo in a concentrated area at one time is pretty spectacular to see over 1,000 of them running around. Also, it's cool to see a couple of them running around doing their own thing and see the crowd interact.
For others, today might be their first but certainly not their last.
