VMNH interpreters and educators visited Beckley Exhibition Coal Mine yesterday and went on an underground tour of the once-active coal mine. The coal mine employs former and active coal miners to lead the tours who add greatly to the experience.
Pictured here (from left to right) is: (front) Gael Chaney, Larry and Carolyn Turner, Christy Deatherage, Evelyn Trent; (back row) Jim Harris, Dennis Reeves, and Joe Ingram.
After the tour of the mine, we were guided through the historic structures on site including a period one-room schoolhouse, a mine superintendent's home, a miner's home, and a reconstructed log-cabin homestead (below).

Participants "mined" the rocks in the quarry looking for good classroom specimens.
Some of the minerals collected included: muscovite mica, biotite mica, garnet, feldspar, quartz, pyrite, and chlorite.
On the way back to the museum, we stopped by a nearby rock formation along the banks of the Smith River. Here Dr. Beard, using a geologic map of the area, talked to the group about the volcanic rock diabase, "...that originated from the mid-ocean ridge zone from the breakup of the Paleozoic era supercontinent Pangea, about 180 million years ago."
When we returned to the museum, Dr. Lauck Ward, curator of invertebrate paleontology, gave a presentation to the group along with the museum's volunteer interpreters on the topic of the mollusks of Virginia's tidewater.

The tour of the museum will go into areas not typically seen by the general public including the scientific labs and the Suzanne M. Lacey Education Center.

Because the Earth orbits the Sun and Earth's axis of rotation is tilted, the length of daylight changes through the year. Summer solstice has the longest period of daylight and the shortest period of night because the northen hemisphere is at its maximum tilt toward the Sun. The length of the daylight varies by latitude, but in Martinsville, Virginia it was 14 hours and 41 minutes (US Naval Observatory).
From now until the fall equinox, the length of daylight will decrease by a few minutes less each day until the length of the day and the length of the night will be exactly equal--known as equinox.

I arrived in Gloucester at about 3 pm and finding that my room was not ready, I drove to Yorktown for the afternoon.
These images were taken in Historic Yorktown on the York River.
