It’s #FunFactFriday so I thought I’d write about the geology seen in Big Bend National Park (Texas). The Chisos Mountains (part of which you see in the image above) are volcanic in origin. One of those volcanic things you’ll see while driving the road through the park are intrusive dikes. Igneous means the rock is volcanic in origin. Dikes are igneous, and they are called “intrusive” because the magma intrudes upon and into the existing rock layers above it. You can see a long stretch of dikes exposed and sticking up out of the ground in this shot. The rocks around the dikes eroded away, leaving those flat-looking walls of rock, sort of like a zig-zaggy-edged rock fence running over the hillsides and up into the mountain flanks.
I’m looking through past Big Bend (as well as other parks) images to see if there are shots I have not edited, or – at the time – didn’t do as good a job of editing. I honestly can’t remember if I ever posted this image or not, back in 2013 (can it be 7 years ago??) captured during my December visit to this national park in southwest Texas. It was my first (out of four) trips there.

Hey folks, it’s Fun Fact Friday! Here are some interesting facts for you about Big Bend National Park, in Texas.
There are over 60 species of cactus, 450 species of birds, 1,200 plant species, and 3,600 insect species found in this national park.
The name Big Bend comes from a bend in the Rio Grande River, which runs along the park boundary.
In 2012, the park was named an International Dark Sky Park, which means it’s awesome for star gazing.
I first visited this national park in 2013 and made 4 more trips there before moving out of Texas. I visited during the winter and spring, when the temperatures were at their most ambient. Late spring was awesome for blooming cactus. And, speaking of visiting, Big Bend is entering it’s busy season, so if you are planning to travel there anytime soon, you’d probably better have alternate lodging plans in case you can’t find an available campsite, according to an article published in today’s edition of the National Parks Traveler.
