Dennis Schmitt, plus three other people walked out over the melting sea ice to the new island. It is located about north of Kaffeklubben Island, at about 83°42'N. Snow and ice had melted to reveal a bank of rocks and sand at a height of about . Later Ken Zerbst failed to locate the island in 2008 while using a helicopter. There are several possible explanations for the failure to locate the island in 2008. The island may not be a permanent land feature connected to the bottom of the sea. Seasonal and yearly accumulation of snow and ice has rendered the island invisible. The island was discovered in a belt of multiyear fast ice, but global warming has eroded this layer of ice along the Greenland coast. Perhaps the island has been exposed to the force of the drift ice and has been 'bulldozed' away. The GPS coordinates for the island's location are most likely inaccurate. GPS satellites are low on the horizon near the North Pole, which may cause a GPS to yield inaccurate results. In late 2004, the Eighth Edition of the National Geographic World Atlas was released. It clearly shows Oodaaq as the northernmost landmass on Earth. In August 2005 and 2006, Peter Skafte, Allen Deforest (satellite engineer), and Paul Lommen (physicist) conducted a search for new islands north of Greenland, using high-resolution satellite images. Two sets of images were obtained, one year apart, to determine if any of the new islands had moved. One island was in diameter and visible on a satellite image, even without magnification. The team named it "Skafte Island" and posted it on a website. They also sent two reports about their findings to Hauge Anderson at the Danish Polar Center, one in 2005 and another in 2006. Dennis Schmitt was shown an image of "Skafte Island" before his departure with a group of people to North Greenland in 2007. He visited the island and made the claim that he had discovered a new northernmost island.
