The A861 Through Glen Tarbert

03395610015710638531918.jpg
Glen Tarbert, Highland, Scotland, UK

Bedrock in the Glen Tarbert area is predominantly psammite ad quartzite of the Glenfinnan Group and Loch Eil Group. This is cut by numerous dykes and the Strontian granodiorite pluton.

Chattanooga, Colorado

07845140015710636784158.jpg
Chattanooga, San Juan Co., Colorado, USA

In 1883, Chattanooga was established as a supply depot for the mines of the Red Mountain Mining District. The first postmaster named the town for his home in Tennessee. The Silverton Railroad arrived in 1887 and the town grew to a maximum population of about 300 people. A major fire in 1892 and the Panic of 1893 doomed the town and the post office closed in 1894, although a few residents remained.

Chattanooga was revived in 1904 when the Silver Ledge Mine built a mill at the site. This time the town survived into the early 1920s.

I suspect the structure shown is part of the Silver Ledge Mill, but I am unable to confirm that.

American Girl Mine

Red Mountain Mining District, San Juan Co., Colorado, USA

I cannot find much information about the American Girl Mine other than it was established in 1882 as a silver mine. Like many silver mines of the American West, it closed as a result of the Panic of 1893. It reopened in 1898 to mine gold.

Agathla Peak

Agathla Peak, Mineral Mining District, Navajo Co., Arizona, USA

Part of the Navajo Volcanic Field, Agathla Peak is a diatreme, the cone-shaped, brecciated conduit of an ancient maar volcano that erupted ~25 million years ago. It is composed of minette, a type of igneous rock with abundant biotite and alkali feldspars. It rises ~457 m (~1500 ft) above the surrounding area.

Agathla Peak is called Aghaałą́ in Navajo and has also been known as El Capitan.

Abajo Mountains (Blue Mountains)

01455680015704676932603.jpg
Abajo Mts, San Juan Co., Utah, USA

The Abajo Mountains consist mostly of porphyritic quartz diorite laccoliths and stocks that intruded Permian to Cretaceous sediments about 26 million years ago.

Minor ore deposits in the Abajos include vanadium-uranium deposits in the Salt Wash Member of the Morrison Formation and some small gold and silver deposits that were unprofitably exploited around the turn of the Twentieth Century.

The Abajo Mountains are also known as the Blue Mountains

Pawnee Mill Stable and Blacksmith Shop, St. Elmo

06816200015686575581357.jpg
Chalk Creek District, Chaffee Co., Colorado, USA

This building is the blacksmith shop and stable for the Pawnee Mining and Milling Company. It was built in 1892 next to the company’s 20 stamp mill. An 1896 edition of The Mining Industry and Review reports the company discovered a large body of ore high in lead and carrying gold. The same report states the company’s mines included the Pioneer, Mollie, Flagstaff, Tressa, and White Cap claims and there were three four-horse teams hauling ore from the mines to the mill.

McKenzie-Ottoson House, St. Elmo

Chalk Creek District, Chaffee Co., Colorado, USA

This rare two-storey cabin (most were one or one and a half storeys) was built around 1885 by the expressman R. McKenzie. It is constructed of peeled logs joined in saddle notches with mud plaster daubing. Other residents of the house included Annie Hovey, Charles Andreen, and Mary Ottoson.

Lava Tube Along Road to Mauna Loa Summit

Mauna Loa Summit, Hawaii Co., Hawaii, USA

Lava tubes form when the outside of a lava flow cools and solidifies but the centre, insulated from the cold atmosphere, continues to flow. Eventually all the liquid lava flows away, leaving the lava tube behind.

Mauna Loa

02858080015681188172963.jpg
Mauna Loa Summit, Hawaii Co., Hawaii, USA

Mauna Loa is a classic example of a shield volcano with a wide profile and very gentle slopes. The earliest eruptions of Mauna Loa began 0.6 to 1 Ma and the volcano rose above sea level ~300,000 years ago. Today, its summit rises ~13,681 feet above sea level. It most recently erupted in 1984.

1935-1936 Mauna Loa Lava Flows

02959700015681187113478.jpg
Mauna Loa Summit, Hawaii Co., Hawaii, USA

On 27 November 1935, Mauna Loa began erupting. When the lava flows threatened the Wailuku River, water source for Hilo, Thomas Jaggar of the Hawaii Volcano Observatory asked the U.S. Army Air Corps to bomb the flow in order to stop the lava’s advance. On 27 December 1935, the lava was bombed. Hilo’s water supply was saved because the eruption ended 2 January 1936. Jaggar was convinced the bombings were successful and ended the eruption. Other scientists at the time and most geologists today are skeptical and believe the end of the eruption was coincidence.
