Carcross desert is a small desert located in the Yukon Territory of Canada, just outside the town of Carcross. It is often referred to as the "world's smallest desert," covering an area of only 2.6 square kilometers. Despite its small size, it is a unique and fascinating landscape, with sand dunes and unusual plants and animals that are not found in other parts of the region.

The Carcross desert was formed around 10,000 years ago during the last ice age, when the area was covered in glaciers. As the glaciers retreated, they left behind sand and silt that formed the basis of the desert. The dry climate and unique geography of the region have contributed to the formation of the desert's distinctive features, including sand dunes and unusual rock formations.

Despite its arid climate, the Carcross desert is home to a surprising variety of plant and animal life. Visitors to the area can see rare plants like the Yukon lupine and mountain avens, as well as animals like the northern pocket gopher, the western toad, and the golden eagle.

In addition to its natural beauty, the Carcross desert is also an important cultural site for the local Carcross/Tagish First Nation. The area has been used for thousands of years as a hunting and gathering ground, and the First Nation has worked to preserve the desert and promote its importance as a cultural and ecological resource. Today, visitors can explore the area on foot, taking in the stunning desert landscape and learning about the history and culture of the First Nation.
