What’s Up? – That time of the Year…

That time of the Year…


Our weather is insane! The temperatures are up and down daily. I do not complaint about it, I’m just reporting what we have weather wise.

  • We are at the time of the year when you hear the crows flying in small groups, early in the morning, making such a ruckus with their ;loud calls., and yes, they love to converse at breakfast time!
  • You can see  a downy woodpecker popping his head from behind objects to stare and I ‘d guess thinking or planning his next move.
  • Or having deputy Mockingbird giving his approval to all the feeders, but of course he would mostly sample the peanuts of his preference.
  • It’s also time of the year when you can see well crafted spider webs appear and disappear every morning.
  • Also, it’s time of the year for Carolina wrens to deliver arias with such vibrant clarity that impress anyone.
  • Let’s not forget the Carolina chickadees working their tails off collecting seeds to keep their provisions for winter up to par.

As you can imagine the bird’s routines continue and there’s always something interesting to make the cold season more entertaining.

H.J.’s Viewfinder – Ruby Falls

Ruby Falls, TN


Ruby Falls is a 145-foot high underground waterfall located within Lookout Mountain, near Chattanooga, Tennessee in the United States.

Geology

The cave which houses Ruby Falls was formed with the formation of Lookout Mountain. About 200 to 240 million years ago (in the Carboniferous Period, at the end of the Paleozoic Era) the eastern Tennessee area was covered with a shallow sea, the sediments of which eventually formed limestone rock. About 200 million years ago, this area was uplifted and subsequent erosion has created the current topography. The limestone in which the cave is formed is still relatively horizontal, just as it was deposited when it was below sea level. The Lookout Mountain Caverns, which includes Ruby Falls Cave, is a limestone cave. These caves occur when slightly acidic groundwater enters subterranean streams and slowly dissolves the relatively soluble limestone, causing narrow cracks to widen into passages and caves in a process called chemical weathering. The stream which makes up the Falls entered the cave sometime after its formation.

Ruby Falls Cave features many of the more well-known types of cave formations (or speleothems) including stalactites and stalagmites, columns, drapery, and flowstone.

The Falls are located at the end of the main passage of Ruby Falls Cave, in a large vertical shaft. The stream, 1120 feet underground, is fed both by rainwater and natural springs. It collects in a pool in the cave floor and then continues through the mountain until finally joining the Tennessee River at the base of Lookout Mountain.

While Ruby Falls Cave combines with Lookout Mountain Cave to form the Lookout Mountain Caverns, the two caves were not actually connected by any passage. Ruby Falls Cave is the upper of the two and contains a variety of geological formations and curiosities which Lookout Mountain Cave does not have.
