2019 June 12, Day Trip Cooks Museum of Natural Science, Decatur Depot, Huntsville, Athens, Alabama

Hubby and I rode to Decatur where we visited the newly opened Cooks Museum of Natural History. 

There we walked through a cave, the forest, the Arctic, and the desert exhibits. 

Cooks Museum of Natural History 

We saw live turtles, saltwater fish, live coral, moon jellyfish, river fish, gopher snakes, American bullfrog, American Alligator, and a variety of insects.

We saw a live beehive with thousands of bees, that was connected to the outside where the bees could collect pollen for the hive. 

A meteorite from outer space, a digital seashell generator, a kinetic sand table, and a tree with a rope bridge to climb were just of few of the inter-actives at the museum. 

Cooks Museum is a place where you can touch, feel, see, and hear different species of animals, reptiles, birds, insects, and fish. 

It is a great place for school groups to visit. 

We had a great time. 

Bee Hive 

We were greeted by a well-informed curator at the Decatur Train Museum. 

He told us some of the histories of the museum.

We saw an engineer running a miniature train around the tracks along its path was a replica of notable buildings of Decatur.

We saw The Princes Theater,  the Old Bank building, the Turner-Surles Community Resources Center, The Train Depot, and the Dance-Polk House.

We saw a Coca-Cola engine, Army Supply Train, Orange caboose, CSX Engine, C& X, K Line, Seaco, ADM Box Car, etc. 

Signs along the walls that read SouthernRailway “The Southern Serves the South”, Rail-Road Crossing, & Will not clear man or side of the car.

Decatur Train Depot Museum 

We saw the early Memphis & Charleston Railroad 1869, steam engines, and carriages cars.  We saw an early telephone hanging on the wall the early Western Union Telegram, maps of early Alabama, and an old Underwood Typewriter. 

On display inside was a Red 1941 Chevrolet 1 2ton pickup truck

On display inside was a Green and Yellow John Deere model “LA” general-purpose tractor 

We shopped at the new Duluth Company Trading Post( located near Intergraph in Huntsville), which had men's and women's clothing.

We ate a late lunch/dinner at Golden Corral. I always overeat at buffets. 

We bought an HP Office Jet 9015 Printer and ink at Office Depot in Huntsville. My old HP had died.

The car was loaded with two cases of water we had bought at Sam's the day before. 

We bought vegetables (cucumbers, tomatoes, squash) from a local grower on our way to Decatur.

We bought a few groceries from Oldies in Athens.
We bought some baking soda at CE Pool where we got our pool water checked. 

So the car was loaded with items to be put away.

I had taken several pictures but was too tired to upload them to the computer. I will do that another day.

Ready for some couch time!

Water for Life

Life on Earth is dependent on clean water. Water quality is defined as the stability of water for a particular use. A definition of good water is different for drinking water than for a lake. Because water is so important for life, we monitor different chemicals, and physical and biological characteristics and work to ensure good water quality. 

Water, Water Everywhere

Water in the ground, called groundwater, is an important source of water on Earth. The ground is different in different places, and some ground materials hold water better than others. An aquifer is an area of ground that holds water well/. Water moves into the ground from rain, snow melt, or other sources. Then it sins until it gets to a layer it can’t move through. This layer might be clay or certain kinds of rock.

Water can fill aquifers, where deep water might remain for hundreds of years, and shallow water can flow to places where it reaches the surface, like ponds, lakes, and springs. 

There is much more freshwater in the ground than on Earth’s surface, and groundwater is drawn out using wells. 

Water Quality=Quality of Life

To evaluate a pond’s ability to support life, we might measure characteristics like the following: dissolved oxygen(DO)-because fish and most other aquatic animals breathe DO: PH-if pHis too far from neutral, either acidic or basic, organisms may be unable to survive; water temperature-warmer water holds less oxygen, so animals might avoid areas of high temperature. In this pond, at certain times, we might also check salinity (the salt concentration).

Freshwater has a salinity of  0 ppt (parts salt per thousand parts water). When Dauphin Island is hit by a hurricane, saltwater may wash over parts of the island and enter the pond or the groundwater. This can affect the island’s human population, who use groundwater in their homes, and also the animals that live in the pond.

These are just a few examples of water qualities that might affect those using the water. 

At Gaillard Lake, you can see where the water table becomes a like surface. When you look at the lake, can you tell oxygen, pH, temperature, or salinity levels? Does the water look dirty?

You may not be able to determine levels by looking, but if you pay attention, you might notice hints bout a lake's water quality. Can you find a diversity of fish, turtles, alligators, frogs, or insects in the water? Are birds feeding from the lake? These signs suggest good water quality, but they are not definitive-sometimes animals are forced to use poor-quality lakes. Water cooler is not a definite marker either - this lake is often a brown color, like tea. This is natural. It is from tannins that leach out of soaking leaves or pine needles.

Aquatic invertebrates are used to assess water quality. Some, like those seen above  (larvae of left to right: caddisfly, stonefly, and mayfly) have a low tolerance for pollution. If they are found in a sample, the water quality is likely good. Others, like the pouch snail and mosquito larva at left, have a high tolerance for pollution. If a sample has mostly animals like these, and very few of those from the first group, water quality is likely poor. 

In the U. S., for water intended for human use, there are established standards, for acceptable levels of dissolved or suspended matter, like bacteria, heavy metals, and others that are potentially harmful. Our municipal water usually follows a path such as this one: water is withdrawn from a natural source: filtered and sterilized; piped into our homes; flushed down our drains; filtered, treated, and the solid waster is taken to one disposal site, while the water is released back to a natural location. Water used in homes on Dauphin Island is groundwater from the island (it is not piped in). Processed water is stored in the water tower seen at right.

Foreign Invasion 

Organisms that arrive in an ecosystem where they did not evolve are called exotic, non-native, or alien. Of those, the ones that harm their new ecosystem are invasive. There are several species on Dauphin Island. A few of them are highlighted below. 

Infiltration 

Plants, animals, and other organisms are moved from their native lands in different ways. These pathways of introduction often involve humans who accidentally or intentionally move them.

A few examples include the release of exotic pets: escape from aquaculture operations; spread from garden plantings; transport in ships ballast water: and transport of fruits and vegetables. As humans move more people and goods around the world, there is more potential for moving organisms into places where they cause harm. 

Setting in: Once they are in a new place, some organisms settle in more successfully than others. Certain factors allow an introduced species to become invasive:

They are adaptable-they can survive in a range of climates, habitats, and soil types; they eat a wide variety.

They reproduce quickly and have lots of offspring. 

They spread out to new areas

Few animals will eat them in the new habitat. 

They competed aggressively for resources. 

How does this affect us?

Biodiversity is the variety of life. It can be defined at different levels, from diversity within a species to that in a particular forest, to that of the entire Earth. The higher the biodiversity for a given area, the healthier the species or ecosystem because it is more resilient to disease or disturbance, such as fire or flood. 

Humans need healthy ecosystems for many reasons. We are healthier with a diversity of organisms for food and medicine. Functioning ecosystems provide important services such as water filtration, oxygen production, and nursery habitat. 

Invasive species threaten biodiversity either by directly killing native species or by taking resources from them so they die or stop breeding.

Galliard Lake and Tupelo Swamp

Cottonmouth 

2-4 feet

AKA water moccasin. This poisonous aquatic snake is thick-bodied and will gape to show its white mouth lining when threatened.

Common Snapping Turtle

6-15 inches. 

Often confused with the less-common alligator snapping turtle, these turtles are not aggressive, unless removed from the water.

American alligator

4-8 feet 

Individuals of this large shy aquatic species periodically “raft” to the island from the rivers north of Mobile.

Florida Smooth Softshell 

6-15 inches

With its flat, leathery shell, this turtle is easy to dust from others. Its death includes crawfish, insects, fish, and frogs. 

Central Newt

2-4 inches

This reclusive salamander prefers quiet pools without fish. The left, a terrestrial intermediate stage, can be found under rotting wood. 

Pig Frog

2-6 inches

This large frog inhabits permanent bodies of water, surrounded by vegetation. 

Their mating call is a distinct, loud, and resonant grunt.

Lists sixes are typical of Dauphin Island representatives

The project was led by Brian Jones, funded by Mobile Bay NEP, and made possible by Dauphin Island Park and Beach Board.

Secret Falls Phil Campbell, Alabama
Secret Falls is one of two falls located in the Dismals, Phil Campbell.
Tucked deep within the foothills of the Appalachians Mountains, Dismals Canyon is 85 acres of nature. 

 The canyon is home to two waterfalls, Secret Falls and Rainbow Falls, and six natural bridges.

Waterfall on Shoals Creek, Killen, Al 

Noccalula Falls 1500 Noccaluala Park Gadsden
Named after a Creek Indian princess, Noccalula Falls stands 90, feet tall and is one of the most visited natural attractions in the state.
When rain conditions are normal the waterfall is around 20 feet with a smaller one located a little to the right of the higher fall. While heavy rains cause the two falls to merge into one wider waterfall.
