These photographs capture the eclipse as it crosses the continental US

A total solar eclipse was last visible throughout the United States 99 years ago, in 1918, and the last time that any states could see a total solar eclipse was in 1979.

From packed campgrounds to towns big and small, solar eclipse seekers along a narrow path in the United States turned their shielded eyes skyward Monday as the moon passed completely in front of the sun. Crowds of people donning special-purpose solar filters cheered and roared as the moon completely blocked the sun and cast a 70-mile wide shadow stretching from OR to SC.

The Eclipse covered a separate part of the United States darkness, led to the fall of temperature, and the glow of the stars and planets in the middle of the day.

It was the first time the U.S. mainland has had a total solar eclipse since 1979, and it was the first nationwide one in 99 years. More than 50 million people live within a two-hours' drive of the 115km-wide totality path.

In Washington, D.C., hundreds of people waited in long lines outside the National Air and Space Museum, which was distributing more than 20,000 pairs of free viewing glasses.

The first point of the moon crossing the sun began at Lincoln Beach, Oregon just after 1:15 pm ET. The event is also live streamed by social network pages of NASA.

"It's all hands on deck", Kentucky's Madisonville Police Chief Wade Williams told ABC News.

The state of OR alone anticipated a million visitors Monday, causing some local hospitals to cancel elective surgeries and call in extra help for the emergency rooms.

Nothing about sports teams bringing people here; nothing about what we need to do or how we should do it. "We just need to enjoy this event".

Millions of Americans have been on the move today, attempting to get into a position where they can best view the historic event.
