Virtual experience brings Grande Cache tourists face-to-face with dinosaur, famous track site

Standing on a wooden platform next to a rocky incline, it's best not to turn around too quickly.

As high up are you are, it's easy to experience vertigo. And there's a job to do: carefully plasterand cast a dinosaur track you've discovered on the side of the cliff.

This is the scenario visitors can experience byslipping on a virtual reality headset at the Grand Cache Tourism and Interpretive Centre, about 400 kilometres west of Edmonton.

Without the virtual reality technology, few would get to experience this remote Alberta heritage site.

The actual Grand Cache Dinosaur Tracksite is on a sheer cliff at the edge of the Rocky Mountains, about 20 kilometres north of the hamlet. It's the onlylarge-scale area of its kind inCanada, according to the Alberta Registrar of Historic Places.

"This is our way of providing that content for individuals who are interested without having to send them, you know, in an unsafe place, or exposing those tracks to the public," said Jenny Daubert, tourism supervisor for the Municipal District of Greenview.

Soon, visitors to Grande Cache will be able to visit and interact with the site virtually through an experience created at Lethbridge College. The work was done by faculty and students participating in theSpatial Technologies Applied Research and Training Initiative.

The dinosaur track site was first unearthed by open pit mining operations atthe former Smoky River Coal Minein 1969.

Along a cliff face stretching about a kilometre, approximately 10,000 dinosaur footprints are embedded evidenceof the creatures who roamed thereduring the Cretaceous period. Due to shifts in the earth, the tracks are now displayedverticallyand are difficult to access.

The area containing the tracksis privately leased, which adds another layer of inaccessibility to the site.

Building a virtual world

In order to take people to the locationvirtually, Lethbridge College instructor and researcher Allyson Cikor visited site with a team and took detailed images of the tracks through a process known as photogrammetry.

The end result, after a little over a year of work, is avirtual experience that offers 360-degree immersionand incorporates spatial audio technology and a narration track.

"It's just really hard to comprehend how many footprints, how big it is, the scale of the site, and also appreciate how hard it is to get there," said Cikor.

"That's the cool thing about the VR project you can sense the scale, you can stand right up to it."

Cikor worked with program graduate Benjamin Blackwell to design the virtual reality experience.

Snapchat dinosaurs

Another part of the tourism centre experience will be an augmented reality scene accessedthrough Snapchat.

Former Lethbridge College student Alexander Mayer, who is now working toward a degree in computer science at theUniversity of Calgary, worked for a month developing the scene that appears after scanning a marker installed at the tourism centre.

Once scanned, a dinosaur appears in the room (when viewed through a smartphone) as dogiant insects, foliage from the time period and shifting ground that eventually reveals the famous tracks people associate with the site.

"I hope it's something that intrigues people," said Mayer, who had never attempted a project like this before.

"It was definitely something that I'd love to do again."

Projects like these highlight the possibilities of preserving important historic sites and allowing more people to access them from just about anywhere, said Mike McCready, the president's applied research chair in virtual and augmented reality at the college.

"Being able to provide ways for people to experience that remotely, in full sense experience, I think isgoing to make a lot of headway in protecting natural and man-made sites."

The Walking with Dinosaurs VR/AR project was funded by the provincial government's Community and Regional Economic Support program and the M.D. of Greenview.

While the virtual reality piece is now complete,the tourism centre is waiting until it is safe to have visitors use the equipment in compliance withCOVID-19 protocols probablyby this spring.

After the finishing touches are put on the Snapchat augmented reality portion, people who visitthe centre will be able to scan a display to view it.

Tourism supervisor Daubert says she hopes one day people will be able to safely enjoy the actual dinosaur track site, but in the meantime the interpretive centreoffers theseimmersive alternatives.

"There is a new kind of push for museums and interpretive centres to have kind of more interactive displays," she said.

"We find that people engage and they retain information a lot more when we can connect with their senses."
