Nope, every square foot of the U.S., Canada and other countries around the world has been explored, surveyed and documented and is under constant surveillance, or on trail cams.
There still are relatively unexplored and remote areas in the US, particularly in wilderness regions and protected areas. However, it's essential to keep in mind that exploration is an ongoing process, and technology and interest in discovery continue to reveal new views of the country. Some examples of unexplored or lesser-known areas include:
Remote wilderness areas: Despite about 50 years of satellite mapping, the US is home to vast wilderness areas in Alaska, the 100 Mile Wilderness in Maine, and side canyons of the Grand Canyon, where rugged terrain and extreme weather conditions have limited human exploration and habitation. These regions remain primarily untouched and offer opportunities for scientific research and investigation.
