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).
Today is the second day of a massive rainfall event throughout southwest Missouri. Here, I recorded 4.69″ of rain yesterday and 3.07″ of rain today, both amounts shattering my previous one-day record for precipitation amounts. Flooding in the creek was at its highest on Saturday night after dark.
Here are more photos of Pearl Creek. The top image, featured in the banner on this site, is at the confluence of Pearl Creek and Sandstone Spring. There is a small waterfall where the spring flows into the pool visible on the right side of the image. This is near the corner of our house and outside of our bedroom window.
The bottom image was taken from the top of the hill looking northwest. You can see the results of a recent controlled burn at the top of the image. The burned area stops abruptly at our north fence.
