Cave Week Theme
"The HOLE Truth about Sinkholes"
Let's hear it
for Virginia Cave Week!
Week promotes an understanding of Virginia's caves and the
surrounding limestone habitats known as karst. Sponsored
by the Virginia Cave Board, the week is used to encourage
educators of all subjects to actively engage their students
from kindergarten through high school using in-class activities
and by visiting one of the state's numerous commercial caves.
This Web site
can be considered a common point for interesting sites having
to do with caving, caving-related education, class-room
activities, virtual caves, and all kinds of other interesting
links. So, select the menu buttons to the left to open pages

Each year offers different areas of focus for VA Cave Week. The theme for 2016 is “The HOLE Truth About Sinkholes!”.
A Sinkhole is a natural depression on the land surface typically shaped like a bowl or cone. Sinkholes are common in regions of karst, where mildly acidic groundwater has dissolved rock such as limestone, dolostone, marble, or gypsum.
Sinkholes can serve as a natural catchment area where surface water enters the subsurface to recharge karst aquifers. Trash and debris dumped into sinkholes can lead to pollution of caves and ground water.
The goal is to increase understanding of sinkholes; to learn how and where they form, the potential threat to groundwater and cave environments if improper management practices are used, provide guidance in proper management of sinkholes, and most importantly to assist landowners-individuals who wish to initiate a sinkhole cleanout project.
Proper sinkhole management and sinkhole cleanout projects are efforts that not only protect the groundwater that becomes our drinking water, but can also result in preservation and restoration of a sensitive biological diversity in karst regions that exist both above and below ground.
Sinkhole cleanout projects are a practical way to protect caves and improve the quality of groundwater in karst aquifers.
