Geologist investigates canyon carved in just three days in Texas flood

In the summer of 2002, a week of heavy rains in Central Texas caused Canyon Lake -- the reservoir of the Canyon Dam -- to flood over its spillway and down the Guadalupe River Valley in a planned diversion to save the dam from catastrophic failure. The flood, which continued for six weeks, stripped the valley of mesquite, oak trees, and soil; destroyed a bridge; and plucked meter-wide boulders from the ground. And, in a remarkable demonstration of the power of raging waters, the flood excavated a 2.2-kilometer-long, 7-meter-deep canyon in the bedrock.

VERY cool! Has anyone ever taken a look at a large shaded relief graphic of North America? Amongst other curiosities, MASSIVE drainage channels from the continental divide eastward.

LOL! The Grand Canyon carved by a glacial ice sheet??? I’m open to new ideas and theories, but damn, just damn. :-))

[editor-surveyor]

Unlawful???

Let’s ping the list for you then...

(I love to do unlawful things...)

Three days? Huh; Texas amateurs!

My access road & driveway had several new canyons after ONE night of thunderstorms.

This year, there's a new pond on the ranch, too; as well as a couple of formerly dry creeks flowing for the first time in decades.

If I could get there from here, I suspect my spring is gushing, instead of seeping, too.

There are recognizable dinosaur types on Amerind petroglyphs in numerous spots in North America. Most interesting is likely the stegosaur (Mishipishu) glyph at Agawa Rock, Masinaw lake Superior:

You mean to say that that isn't the little-known Long Tailed Mohegan Mastodon? sar>

Bet Job would have recognized it, and that he had a name for it: Behemoth.

LOL!

Are you sure?

I think they have miles, yards and feet in Texas.

[ApplegateRanch]

You may laugh, but the squash patch is now in the potato field, and the potatoes are stretched throughout the pasture, and on down 6 miles of canyon, all the way to town.

The real bad news was the wind: we walked out a couple of days ago to find that all three of the turkey roosting snags on top of the ridge had blown down. I doubt that we were as unhappy as the turkeys, though. They have roosted there since long before we bought the ranch in 97.

[wendy1946]

No, the behemoth would have been a larger sauropod dinosaur. Mishipishu, or "water panther" in Ojibway language is described in Amerind oral traditions has having a sawblade back, red fur, and a "great spiked tail" which he used as a weapon. That's a stegosaur. Mishipishu glyphs were common when Europeans first got here and Lewis and Clarke described their Indian guides as being in mortal terror of them. They appeared around rivers and lakes and were meant as warnings, i.e. "One of these lives here, be careful". There are only a few of them left now. Amerind artists touch the things up every few decades or so and the horns on the Masinaw glyph were obviously added long after the last stegosaur died out; real stegosaurs didn't have horns.

But given the standard theory we were indoctrinated with in school in which dinosaurs died out tens of millions of years ago, the idea of drawing ANY creature with a sawblade back would never have occurred to anybody.

[ApplegateRanch]

Yes, that description is a stegosaur. Never came across these glyphs existence before. Thanks for the information.

[metmom]

Yet another example of some geologic event happening faster than expected.

[wendy1946]

You might have noticed... the people telling us that stegosaurs died out 70,000,000 years ago are the same people telling us that modern humans and Neanderthals had a common ancestor 800,000 years ago...

Thanks for the ping!

I grew up near there and have spent many wonderful days along the Guadalupe River and then on Canyon Lake after the dam was built.

I remember vividly being on the top of a ridge above the area which would become indunated by the lake water. An engineer was showing me where the water conservation level would be at my feet. Looking down into the basin far below and miles away was a huge caterpillar crane. It looked about the size of a very small pea.

The engineer told me the lake was projected to fill about seven years after the impoundment began. I thought about the enormus amount of water that would be necessary to fill the lake and couldn’t believe it would ever happen.

But the rain gogs smiled and water-short Texas had some good years of rain. The lake filled in about two years, well short of predictions.

Thank you. Show me a three day canyon in granite and we will talk.

RE Behemoth

What kind of animal is it as described in the book of Job ?

JOB CHAPTER 40:

15 Behold now the behemoth that I have made with you; he eats grass like cattle.

16 Behold now his strength is in his loins and his power is
in the navel of his belly.

17 His tail hardens like a cedar; the sinews of his tendons are knit together.

18 His limbs are as strong as copper, his bones as a load of iron.

19 His is the first [largest] of God’s ways; [only] his Maker can draw His sword [against him].

20 For the mountains bear food for him, and all the beasts of the field play there.

21 Does he lie under the shadows, in the cover of the reeds and the swamp?

22 Do the shadows cover him as his shadow? Do the willows of the brook surround him?

23 Behold, he plunders the river, and [he] does not harden; he trusts that he will draw the Jordan into his mouth.

24 With His eyes He will take him; with snares He will puncture his nostrils.
