Thank you. Appreciate you watching.

Thank you. I am glad you enjoyed it. I was surprised by High Island. Really like the area…. Minus the mosquitoes. 😀

It would have been great to walk on a pier there. I really enjoy the gulf coast. Thanks for sharing.

Thanks for sharing. I am not to familiar with those formations but would love to learn more. I need to plan a trip out there to do a video. Appreciate the comment and thoughts.

Nice! Are you going for the bird watching?

Thank you so much for the kind words. I am glad you enjoyed the episode. I drove over it before and had no idea. It is a subtle feature. Hope you can stop and check out some of them next time you drive over it.

@@earthandtime5817 I’ll be driving this area in late August. I’m gonna stop and check out the cemetery and maybe stop at Boy Scout woods and I’ll take a walk around the trails

@@rkmatt8761 enjoy all of the birds. I will be curious how many types you will see. Also one tip: bring mosquito repellent. They can get bad in the woods.

Good question. When mapping in the basin and range I would use changes in vegetation to help me find changes in geology. There is an intimate link between geologic structures and foliage. Thanks for the comment.

Sometimes the fossil material is under so much pressure that extraction is actually a release of pressure rather than a vacuum. That's why a typical depiction of an oil strike is the "gusher," and also why oil well fires are so difficult to put out: sometimes the fossil material naturally can just spray out of the well up into the air, and if it's on fire, it's a massive torch that is impossible to get near. When pressure in an oil well drops, there are procedures that oil companies can use to counteract the formation of a vacuum. This sometimes takes the form of pumping inert clay or sand into the well-- not to fracture the bedrock, as in hydrological "fracking," but to artificially boost the pressure that the oil is under to keep it flowing. The engineers who work on these oil wells have to periodically evaluate wells to determine if those expensive measures would be cost effective. Does that answer your question?

Great question and excellent response!

@@michaeltichonuk2176 Thank you. I appreciate the feedback. 😁

@@k.jespersen6145 I agree, that was an awesome, detailed reply. Thank you. BTW.... the reason I'm interested in the possibility of cavities forming during mining activity, is because I grew up on a small gold-mining town in South Africa's northern provinces and the town is situated in a dolomite rich area which erodes easily. In fact the erosion was so intense in some spots that huge sinkholes would open up from time to time. As a child I remember being terrified of going to bed at night for fear that the earth would swallow our house like what happened to the Oosthuizen family about 10 km from where I lived. Also, our town had 5 schools and one of those had to be evacuated because the earth was giving way in spots. All of the above was exacerbated by tremors caused by mining activity ...blast work that could be felt at the surface further destabilizing the already fragile subsurface. It was horrible living in a place where you had to fear every little tremor not knowing whether the swiss cheese structure underneath your feet is going to give way and swallow you whole. Anyway, thank you again for your excellent answer.

@@JacquesMare thanks for the question and sharing your experience. Luckily salt domes and the surrounding sediments here don’t react the same way as dolomite or limestone which both have the potential for sinkholes (think this could be a good topic for a video) due to karsting (water eroding them in the ground). Appreciate the comment.
