Dolores Canyon

Grandiose

Indeed! Thanks!

A striking landscape with all that red rock! The place names are cool- Paradox valley:-)))

Thanks! The Paradox Valley was named by Albert C. Peale in 1875, a member of one of the surveying expeditions that was a precursor to the USGS, because of the "paradoxical" course of the Dolores. It cuts directly across the valley perpendicular to its long axis, flowing out of this canyon on the south and into another canyon on the north. You'd expect a river to be along the long axis of the valley! But in fact the valley has nothing to do with the watercourse--it's a collapsed anticline, one of the famous (in geologic circles) salt anticlines of SW Colorado and adjacent Utah. Salt in the core of the anticline dissolved out to cause it to collapse.

So there's a reason to even the most paradox names- and an interesting one!

So what controls the tamarisk beetles?

Starvation. They can only eat tamarisk--that was researched in some depth before they were introduced! Now we just have to hope they don't mutate-- ;)

At least they did their homework before unleashing them.

I suspect the beetle responds to chemical cues from the tamarisk that mean it's "food." So, as long as it doesn't begin responding to other compounds given off by other plants, all is well--

We hear far too often of 'cures' that end up being problems. Unfortunately I've never seen any statistics on the long range effects of such cures.

Magnificent capture!

Indeed! We wished we'd had more time.

Spectacular country, glad the beetles are doing their appointed job.

Let's just hope they don't develop a taste for something else!

Tolles Landschaftsbild !!

Thanks!

Well, hopefully the beetle does the job!
