Eocene Yegua Formation Petrified Wood

A projection of rain in the forecast for Saturday caused me to change my plans at the last minute and venture a little further west than I had initially planned and hoped to go. Since I had not yet visited Whiskey Bridge since moving to Texas at the beginning of September I decided that it posed as a nice alternative, especially when trying to decide on Friday night where to go the following morning. Plus this way I could also collect some petrified wood in College Station. This petrified wood is from the Late Middle Eocene Yegua Formation and is absolutely abundant in the Bryan-College Station area. Petrified wood chips literally cover the ground. Whether recent rain from Tropical Storm Nicholas unearthed a number of pieces or I simply lucked out with the site having not been collected in a while, but in about an hour of collecting, I found more than a dozen good size chunks of petrified wood. I was really impressed by the diversity of colors and how many of the pieces looked like pieces of wood you would find today. Several pieces had knots in them, showed insect damage, or had small deposits of chalcedony or druzy on them. All of my finds were either tropical hardwoods or tropical conifers. After having my fill of petrified wood, I made my way to Whiskey Bridge and had the site to myself for the entire day. I am still working on cleaning, stabilizing and identifying all of my finds, so a post on my Whiskey Bridge finds will have to wait for another day.

You got some pieces with nice features. I would say nobody has hit that spot in a while and the recent rains worked in your favor.

I love the pieces that resemble recently cut wood as well as those with interesting mineral and crystal structure. Looks like you scored big. Congratulations Mike and thanks for sharing.

Very nice petrified wood and I look forward to seeing your Whiskey Bridge finds, that is a fun spot.

On Monday I had to drive through College Station on my way to another fossil site so I decided to make a return visit to where I found the pieces of petrified wood. The plan was to try to extract a piece of wood that wouldn't budge the last time I was there. It was found in close proximity to the pieces with crystals on them so I suspect that it might also have crystals on it. Recent heavy rains must have reburied the piece because I could not locate it. However, since I was already there, I did a quick search around the rest of the site and ended up stumbling on this huge chunk of petrified wood. It is roughly 15 inches at its longest and 10 inches at its widest.

Wow, some of those pieces look like they could have come from the small firewood pile outside my front door. That’s cool to see in a petrified piece!
