Banff Alberta - Tourists got quite the wildlife show this weekend, when a pack of Banff wolves killed an elk on a railway overpass as witnesses snapped photos.
 
The takedown led to an hour-long spectacle that required trains to slow while wildlife officers removed the carcass.
 
It began Sunday morning when some visitors in Banff National Park witnessed wolves attacking the cow elk.
 
Witnesses reported the incident to dispatch.
 
"The elk was actually killed by the wolves right up on the middle of that overpass," said Steve Michel, human/wildlife conflict specialist with Banff National Park.
 
"Wildlife staff attended and confirmed it. There were a number of people there taking photos, as well."
 
It's the same railway overpass where a photo of a herd of elk crossing it went viral in 2007.
 
In the Sunday incident, Parks Canada staff notified CP to slow down the trains through the area so they could remove the elk carcass to prevent any of the wolves from being hit.
 
Michel said they would normally leave the carcass out for the wolves to eat, but there was no where they could leave it safely so it's been stored in a large freezer until they can put it back on the landscape in a secure location.
 
"We'll get those back out onto the landscape in the spring," he said.
 
"It's unfortunate, we always like to give them the opportunity to keep it in the location where it's been killed, but it doesn't always work out that way."
