Who discovered Colorado?

Answer 1

No one discovered Colorado in 1876.

In 1803 it was part of the Lousinana Purchase.

In February, 1861, Congress took parts of Utah, New Mexico, Kansas and Nebraska to make a new territory called Colorado.

In 1876 Colorado achieved statehood.

Answer 2

Francisco Vasquez de Coronado,governor of a province in Mexico, led an expedition northward to search for the legendary "Seven Golden Cities of Cibola". But the "cities" they found were sad little pueblo villages, and there was no gold. Coronado and his men found the Grand Canyon on the Colorado River, but, again, no gold. However, Coronado's expedition gave Spain a claim to the vast lands of the American Southwest.
Spain first visited Colorado and claimed it. Later in the 1800s the U.S. bought it in the Louisiana purchase.
