A team of scientists working in the northernmost region of the Canadian Arctic have made a staggering discovery. While measuring ice density for climate change research, the team discovered a 2,000-year-old frozen artifact.

"Behind the ice, we saw a circular round object," said researcher Evan Creswell. "It was two pieces of bread. In between the bread was a thin patty of meat. And, of course, also tucked in there was a sliced tomato, lettuce, pickle, chopped onion, and what appeared to be mustard."

Many people describe the found object as a sandwich. Others say it more closely resembles a hamburger. But Creswell isn't so quick to apply any labels to his discovery.

"You have to go through the scientific process. I'm referring to it as a found object," he told This Is That. Although he admits: "It would be highly unusual for these different ingredients to just simply be pushed together by the movement of ice. Possible, but very unusual."

Through measurements of the depth at which the found object was discovered, and by carbon dating on the lettuce, Creswell has determined that the object is somewhere between 1,800 and 2,200 years old.
