What Are the Miller Bluffs?
The Miller Bluffs are like a long, natural wall of rock. They are very steep and face the rising sun. Imagine a giant cliff that goes on for many kilometers! They are a part of the amazing icy landscape of Antarctica.
Where Are the Miller Bluffs Located?
These impressive bluffs are found in the Ellsworth Mountains in Antarctica. Specifically, they are in the northern part of the Sentinel Range. They start near a place called Foros Spur and the mouth of the Newcomer Glacier. From there, they stretch northwest along the side of Gromshin Heights. This makes them an important landmark in this icy region.
How Were the Miller Bluffs Discovered and Mapped?
Exploring Antarctica is a big challenge, and discovering features like the Miller Bluffs takes a lot of effort. These bluffs were first seen from the air and later carefully mapped using special photographs.
Early Flights and Photos
The northern end of the Miller Bluffs was first seen and photographed by an explorer named Lincoln Ellsworth. He took pictures of them on November 23, 1935, during his pioneering flight across Antarctica. This was a very early way to explore and record the features of the continent.
Mapping from the Sky
Later, in 1961, the United States Geological Survey (USGS) created detailed maps of the bluffs. They used air photos taken in 1959 by a U.S. Navy squadron called VX-6. These aerial photographs helped scientists understand the exact shape and location of the bluffs.
Who Are the Miller Bluffs Named After?
Many places in Antarctica are named after people who have contributed to exploration or scientific research. The Miller Bluffs are named in honor of a very important person.
Why Was George P. Miller Honored?
The bluffs were named by the Advisory Committee on Antarctic Names. They chose to honor the Honorable George P. Miller. He was a former chairman of the House Science and Astronautics Committee. This committee helps decide on scientific projects and space exploration for the United States. Mr. Miller was very interested in activities in Antarctica. His support helped make sure that U.S. research on the continent was successful from 1958 to 1972. Naming the bluffs after him was a way to recognize his important help.
