Glen Rose Interlude – 2

Want to know what you missed? Go back and catch up.


The main reason most people have for visiting Glen Rose, Texas is for dinosaur tracks. Whether it’s to visit Dinosaur Valley State Park or the oxymoronic Creation Evidence Museum up the road, it’s all about dinosaur tracks. Before one Roland T. Bird came into downtown Glen Rose for a glass of lemonade and found a dinosaur track incorporated into a WPA-built bandshell next to the courthouse, the town was one of a multitude of towns southwest of Fort Worth boasting scenic views and excellent diners, but nothing that would convince people to travel from the other side of the planet to visit. Now, Glen Rose has a plethora of antique stores and art galleries to give a reason to stay, just so long as you don’t spend so much time stomping around in the Paluxy River that you lose track of daylight.

Since the original plan to go slopping around in the Paluxy was capsized by the closest thing to white water that I’ve ever seen on it, this meant lots of daylight for other endeavors. The dinosaur trackways are on what used to be muddy beachfront, so they tended to catch lots of other items during regular rounds of sediment deposition. While I have yet to come across any reports of actual dinosaur bone preserved in Glen Rose, that mud preserved a lot more. In particular, the area is simply rotten with exquisitely petrified driftwood, most of which looks as if it came out of the surf last week instead of 120 million years ago.


Those familiar with the fossilized logs at Petrified Forest National Park in Arizona might be a bit disappointed with Glen Rose petrified wood, or most of the stuff in Texas for that matter. The Glen Rose deposits rarely preserve whole logs: the vast majority of pieces resemble the chunks and bobs that wash up in the Gulf of Mexico today: the bark is gone, but the surf wasn’t strong enough to move big logs and stumps onto land, so most of what’s here are smaller pieces that were broken up elsewhere. However, it’s beautifully silicified, preserving knotholes and insect damage, and it’s considerably more forgiving of erosion than its mudstone matrix, so it once collected in large piles. A tough but workable stone, with obvious attractiveness and durability: when given that sort of resource for construction, of course the people Glen Rose put it to use.


Based on the buildings still extant incorporating local petrified wood, you’d think that the area would remain loaded with logs. Making a trip out to Glen Rose 15 years ago, I heard some of the backstory from the former mayor, who ran a now-defunct bookstore in the town square. According to her, most of the available logs and larger chunks that weren’t already incorporated into local buildings were picked up and sold for the rock shop trade in the 1950s, and the high quality of the wood meant that people were keeping a close eye on the buildings. She related how a gas station near the square, made almost completely out of local petrified wood, had shut down and the land purchased by a local church for possible expansion. According to her, the church was evenly split between those who wanted to restore the gas station as a piece of local history and those who wanted to sell the petrified wood to a wholesaler, and this was settled when the gas station “accidentally” came down in the middle of the night. The petrified wood was salvaged and sold, and half of the congregation hasn’t talked to the other half since.


Even acknowledging that (a) the story might be apocryphal and (b) I should have taken notes rather than depending upon memories from a decade-and-a-half ago, the gas station story is believable upon seeing the structures still standing. So long as Cretaceous rock remains in the Glen Rose area, additional petrified wood will eventually erode out and gradually migrate to the bottom of the valley, but all of the easy pickings have been gone since the Great Depression. With luck, though, enough will remain that some aspiring palaeobotanist should be able to identify and classify the local flora, and give as much of a view of the plant life of Creataceous Glen Rose as the trackways give of the fauna.
