VISIT OUR UPDATED WEBSITE

Over the past few months, updates were made to the Project Bedrock website. The previous website was hosted on a platform that had limitations and technical issues. Anticipating challenges with the development of the new D-MAP Tool website, a decision was made to migrate the site to WordPress and engage a webmaster. This transition allows both the Project Bedrock and D-MAP websites to operate smoothly together, given that the D-MAP site will also utilize WordPress.
While much of the content remains unchanged, several enhancements have been implemented, including the addition of the latest newsletters on the homepage. Additionally, new members have joined the D-MAP team. The D-MAP Tool page now provides more detailed information, serving as a preview for the upcoming website. The karst country library is also undergoing updates and will soon include its own search feature.
So go check it out!

GRAND PRIZE WINNER: GEARY SCHINDEL

Each year, the Hill Country Alliance produces a monthly calendar that showcases photographs contributed by its supporters. Geary Schindel, a karst geologist helping us with the D-MAP Tool, won the grand prize for his photograph taken inside the Devil’s Sinkhole.

The Devil’s Sinkhole, located near Rock Springs, is a dramatic example of a solution sinkhole. Solution sinkholes develop in karst regions when acidic water, resulting from rain and carbon dioxide, dissolves soluble limestone bedrock, leading to the formation of underground cavities. As time passes, the limestone above these voids can weaken and collapse, resulting in the sinking of the surface and the creation of a sinkhole.
In karst regions, saturated soils during heavy storms can lead to the formation of sinkholes, which may act as natural drainage systems. This process of rainwater moving downward can reduce surface runoff and assist in the replenishment of deep groundwater and aquifers. Read this paper to learn more about current sinkhole research.
