(CNN) -- [Updated 3 p.m. Monday, March 12] This photo was taken on South Georgia Island, "an untouched natural paradise of penguins, seals and birds," according to iReporter Jonathan Pozniak.
Pozniak recently visited the remote, barely inhabited British territory, which is southeast of Argentina near the bottom tip of South America.
"We celebrated Mass in the old whalers church (even us nonreligious types couldn't pass up the once-in-a-lifetime experience), hiked up to an elevated lake in the mountains and spent the next few days sailing and exploring the bays, fjords and penguin rookeries around the island," he told CNN. "For us, it defined the word remote and gave us a glimpse of Mother Nature most people don't get to see."
The island is also the final resting place of famed polar explorer Ernest Shackleton.
