The Hayden Geological Survey of 1871 explored the region of northwestern Wyoming that later became Yellowstone National Park in 1872. It was led by geologist Ferdinand Vandeveer Hayden. The 1871 geological survey was not Hayden's first, but it was the first federally funded geological survey to explore and further document features in the region soon to become Yellowstone National Park, and played a prominent role in convincing the U.S. Congress to pass the legislation creating the park. In 1894, Nathaniel P. Langford, the first park superintendent and a member of the Washburn-Langford-Doane Expedition which explored the park in 1870, wrote this about the Hayden expedition:

Geological survey in the context of Geological Survey of Canada
The Geological Survey of Canada (GSC; French: Commission géologique du Canada, CGC) is a Canadian federal government agency responsible for performing geological surveys of the country developing Canada's natural resources and protecting the environment. A branch of the Geoscience and Earth Monitoring Sector of Natural Resources Canada, the GSC is the country's oldest scientific agency and was one of its first government organizations.

Geological survey in the context of Ludovic Mrazek
Ludovic Mrazec (July 17, 1867 in Craiova – June 9, 1944 in Bucharest) was a Romanian geologist and member of the Romanian Academy. He introduced the term diapir that denotes a type of intrusion in which a more mobile and ductilely deformable material is forced into brittle overlying rocks. The phenomenon of "diapirism" allows rock salt to provide an effective trap for hydrocarbon deposits. In this way, Ludovic Mrazec explained the distribution of hydrocarbon accumulations in the Neogene Carpathian. Diapirism is commonly used as a basic concept in geological survey as well as in Planetary science.
