McKinney Falls State Park is home to the fascinating Pilot Knob Volcano, an extinct submarine volcano that played a significant role in shaping the park’s unique geological features. As a state park touring enthusiast or tour planner, understanding the impact of this ancient volcano can greatly enhance your experience and appreciation of this natural wonder.
What type of volcano is Pilot Knob Volcano in McKinney Falls State Park?
Pilot Knob Volcano is an extinct submarine volcano that was active during the late Cretaceous Period, approximately 65-100 million years ago. It is part of a group of around 75 volcanoes scattered across Central Texas, including the areas of Austin, San Antonio, and Del Rio.
How did the extinct Pilot Knob Volcano impact the formation of the waterfalls in McKinney Falls State Park?
The Pilot Knob Volcano erupted and spewed debris into the surrounding sea during its active period. Over time, the softer volcanic debris eroded faster than the hard limestone, leading to the formation of the waterfalls in McKinney Falls State Park. The streams of soft volcanic debris eroded faster, undercutting the limestone and creating the falls over millions of years.
What geological features are visible in McKinney Falls State Park due to the presence of the extinct Pilot Knob Volcano?
The park features two stunning waterfalls, the Upper and Lower McKinney Falls, which were formed due to the erosion of the limestone by Onion Creek. The creek’s water continually carves out the limestone, creating the waterfalls and homes. Additionally, the park has a prehistoric rock shelter that has been used by humans for over 4,000 years, providing a glimpse into the area’s rich cultural history.
