Greater than 40 years in the past, Apple pulp and shouting helped save numerous mule deer from being hit by dashing visitors on Interstate 80 close to Elk Mountain.


In the course of the winter of 1977-78, John Hyde was a recreation warden trainee with the Wyoming Sport and Fish division and charged with determining methods to get deer to make use of freeway underpasses which might be nonetheless in use at present.

“I baited the underpasses with all kinds of stuff, including lettuce scraps from grocery stores,” Hyde advised Cowboy State Every day. “We discovered that apple pulp labored the very best.

“Apple pulp is used everywhere to bait all kinds of animals; I guess because of the sweetness of it.”


Hyde went on to have a 35-year profession as a recreation warden. He’s now retired and lives in Lovell.

Underpasses Supplied Hope


When that part of I-80 was constructed in the course of the early Seventies, it reduce proper by means of considered one of Wyoming’s largest mule deer migration routes, Hyde stated. Sturdy 8-foot woven-wire fences had been constructed alongside both aspect of the freeway to maintain deer off the street.

There are also just a few underpasses alongside that stretch, however they weren’t initially meant as wildlife crossings, Hyde stated. As an alternative, they had been put there to permit farmers and ranchers to maneuver gear between pastures and fields on both aspect of I-80.


It quickly grew to become obvious that the underpasses additionally may turn out to be useful as a technique to get deer safely throughout, Hyde stated.

At first, the deer would simply crowd up in opposition to the fences, he stated. Generally they’d injure or kill themselves attempting to get by means of. Or, they’d get struck by visitors once they did handle to breach the fences.

“I used to patrol that stretch of highway checking for deer mortality, and I saw a lot of it,” Hyde stated. “And you would see deer by the hundreds just piling up against those fences, not sure what to do.”

The trick was getting deer to make use of the underpasses.

Shock, Shouting Moved Cussed Deer

As soon as Hyde and his compatriots found how properly apple pulp attracted deer, the following downside was getting them to really transfer by means of the underpasses.

That’s as a result of they’d simply bunch up contained in the underpasses to gorge themselves on the pulp, however they wouldn’t by means of to the opposite aspect, he stated.

So, Wyoming recreation wardens figured they’d give the deer a nudge by startling them.

“We’d come up the highway in our truck, and they’d be down there (in the underpasses) eating,” he stated. “We’d hop out of the truck, go down over the side of the highway and start waving our arms and yelling at them to move.”

However the deer had been cussed.

“It took about a month to six weeks of doing that. But eventually, the deer caught on, and they started using the underpasses on their own,” Hyde stated.

Full Circle

Whereas these efforts in the course of the Seventies actually helped, that stretch of I-80 stays troublesome. The part between mile posts 247-256 close to Arlington nonetheless sees roughly 150 wildlife collisions a 12 months, in accordance with the Wyoming Sport and Fish Division.

To mitigate that, a wildlife overpass is deliberate at Halleck Ridge close to Elk Mountain. No begin date for the undertaking has been set. It is going to be partly funded by means of a $10 million appropriation for wildlife crossings that was requested by Gov. Mark Gordon and granted by the Legislature.

Wildlife overpasses now have changed underpasses in lots of locations throughout the West, Hyde stated.

“Now overpasses have come home, so to speak, to the place where it all began – I-80 near Elk Mountain,” he stated.
