During the Triassic, central Virginia was a rift basin. [1] Brachiopods were still present in Virginia during the Mesozoic. [4] On land, the early Mesozoic plants of Virginia included Equisetales, gymnosperms, Cycadeles, cycads, and conifers. This flora is almost identical to that from contemporary deposits in North Carolina. [4]
Juniperus virginiana foliage and mature cones. Juniperus virginiana is a dense slow-growing coniferous evergreen tree with a conical or subcylindrical shaped crown [8] that may never become more than a bush on poor soil, but is ordinarily from 5–20 metres (16–66 feet) tall, with a short trunk 30–100 centimetres (12–39 inches) in diameter, rarely to 27 m (89 ft) in height and 170 cm (67 ...
Most conifers are monoecious, but some are subdioecious or dioecious; all are wind-pollinated. Conifer seeds develop inside a protective cone called a strobilus. The cones take from four months to three years to reach maturity, and vary in size from 2 to 600 millimetres (1 ⁄ 8 to 23 + 5 ⁄ 8 in) long.
Unusually for a pine, the cones normally point forward along the branch, sometimes curling around it. That is an easy way to tell it apart from the similar lodgepole pine in more western areas of North America. The cones on many mature trees are serotinous. They open when exposed to intense heat, greater than or equal to 50 °C (122 °F). [16]

At the same time, 250 to 300 quarries were producing limestone, granite, slate, soapstone and gravel. Willis Mountain, near US 15 between US 60 and US 460 hosts the largest kyanite mine in the world, supplying the automotive spark plug and high-temperature kiln industry. Virginia also has significant vermiculite production. [10]
Inside the centennial time capsule, officials found 15 artifacts dating back to 1924 and earlier, including a film of the 1921 groundbreaking for the memorial, the 1917 Declaration of War and a ...
