That's what more than 1,200 elk are, rumbling through the snow in one herd.
And that's how state Game, Fish & Parks Department wildlife manager John Kanta described the herd he saw last week near Jewel Cave National Monument west of Custer during an aerial elk survey.
"It was the most elk I've ever seen in one place in the Black Hills," Kanta said. "It was pretty amazing."
It wasn't just amazing to Kanta, either.
Mark Stott, a Perryman, Ore., helicopter pilot who has flown over herds in some of the nation's top elk ranges, has never seen one bigger, either.
“It was the most elk I’ve ever seen, too,” Stott said. “And I do this for a living.”
Stott works for Alaska-based Quicksilver Air, Inc., which is working under contract with GF&P on the comprehensive aerial survey of elk in the Black Hills. GF&P is contracting for this work, which began in mid-February and is continuing this month, to get a better count on the Black Hills elk herd.
It also seeks to answer critics of GF&P big-game management, who question the department's 2012 estimate of elk population of 4,000 in South Dakota's part of the Black Hills, which also extend into Wyoming.
Kanta and Stott saw more than a fourth of that estimate in one place last week. And Kanta said the 1,200 estimate was probably conservative.
It was big enough and scattered enough that it took two pictures to capture most of it.
But Kanta also said there were other areas of the Black Hills where elk were very scarce.
"We're not done yet, but so far this survey has shown me that we have areas with great numbers of elk and other areas that are almost devoid of elk," he said. "I certainly think there is work to be done to bring numbers back in some areas."
Two helicopters and their crews from Quicksilver Air engaged in some of that work last week. They took part in a helicopter drive that pushed more than 200 elk out of Wind Cave National Park into adjoining Custer State Park and national forest.
Another helicopter drive may take place later this week or early next as Wind Cave officials cooperate with GF&P to reduce the elk population in the park. The aerial survey work, however, is their primary duty here.
The two helicopters have been landing on and taking off from the parking lot in the shop-garage area of the Outdoor Campus-West in northwest Rapid City. The helicopters are kept in a garage overnight.
Kanta and another GF&P wildlife specialist ride with the pilots to help direct the survey and observe and photograph elk.
The helicopters also are fitted with cameras that shoot stills and video.
It's unlikely that any image will top those caught last week of the large elk herd in a generally open area known as the Jasper Burn. The Jasper Fire burned 83,508 acres in August of 2000, initially devastating the forest area there.
But the resulting open meadows and diversity of grass and other vegetation favored by elk has also been a magnet for the large members of the deer family, which seem to be thriving there.
"They like those open areas with that good grass to graze on," Kanta said.
Kanta said the population and distribution information from the survey will help GF&P manage the Black Hills elk herd. That management work included designing hunting seasons and determining how many licenses to issue.
"The population estimate allows us to model the population and test different harvest strategies before implementing so that we know what kind of impact we may have on the population," Kanta said.
That's the practical part of the aerial survey. But there's room, too, under those whirling helicopter blades for simple amazement.
Which is just what Kanta experienced when he saw that Jasper Burn herd.
