Sinkholes are numerous on the karst landscape of the Ozarks, but are often overlooked. After a large rainfall event, sinkholes throughout the area temporarily fill up with water and become ponds. During most events, falling rain percolates through the karst system in these various sinkholes quickly enough that water doesn’t accumulate above the surface. With at least 7″ of rain over 48 hours, there are plenty of sinkholes that cannot drain quickly enough. All of these photos are between Pearl Creek Farm and Cotner’s Corner (US 160 and MO 123 junction).
I love data. It turns out there’s a lot to track around the farm and I keep a variety of databases to do the heavy lifting for me. My database of choice is PostgreSQL, a poster child for open source software, which probably means nothing unless you’re a geek like me. This post is the first in a series that shows the various ways that we do science at Pearl Creek Farm!
Although Sunday night was supposed to be as low as it was going to get, it actually got quite a bit colder on Monday night. Fortunately, the temperature didn’t get much colder than this during the overnight hours. In fact, it warmed up and we woke up to a balmy 2oF above zero!
I’m hoping this “polar vortex” scoots on out of here for the rest of the winter. I think we’ve all had enough of it.
But, the biggest news is the bitter cold we’ll endure all day. It won’t get to 10oF today, probably. This is the first temperature below zero that I remember here, although I didn’t start keeping detailed temperature records until 2011. Stay warm!
During the year, we keep a list of species we’ve observed. Right now, the list is confined to vertebrates (sans fish) and plants, as that is our primary area of expertise. The vertebrates are kept on a list while the plants are kept in our head (for now).
