S P Crater is a cinder cone volcano in the San Francisco volcanic field, 25 miles (40 km) north of Flagstaff, Arizona, United States. [4] It is surrounded by several other cinder cones which are older and more eroded. It is a striking feature on the local landscape, with a well-defined lava flow that extends for 4.3 miles (7 km) to the north. [5]
No 4-6-4 tender locomotives saw service in South Africa, but six 4-6-4T tank locomotive classes were used, all of them on 3 ft 6 in (1,067 mm) Cape gauge. In 1896, the Natal Government Railways (NGR) rebuilt one of its Class K&S 4-6-0 tank locomotives to a 4-6-4T configuration, as directed by NGR Locomotive Superintendent George William Reid.
Union Pacific Challenger No. 3985 is an example of a 4-6-6-4 locomotive. In the Whyte notation for classifying steam locomotives by wheel arrangement, a 4-6-6-4 is a railroad steam locomotive that has four leading wheels followed by two sets of six coupled driving wheels and four trailing wheels . 4-6-6-4's are commonly known as Challengers .
The Hudson wheel arrangement A steam locomotive with a 4-6-4 wheel arrangement [30] [117] Hump A raised section in a rail sorting yard that allows operators to use gravity to move freight railcars into the proper position within the yard when making up trains of cars. This is faster and requires less effort than moving cars with a switching ...
In issue 33, Mad published a partial table of the "Potrzebie System of Weights and Measures" developed by 19-year-old Donald E. Knuth, later a famed computer scientist. According to Knuth, the basis of this new revolutionary system is the potrzebie, which equals the thickness of Mad issue 26, or 2.263 348 451 743 817 321 6473 mm. [4]
The Cinders are part of the Black Rock Desert volcanic field. The lava of The Cinders is basalt of late Holocene age. The basalt erupted from the vent at the Ice Springs craters less than 700 years ago (as of 2020). [2] It is the youngest basalt flow in Utah. To the south is a somewhat older lava flow surrounding Tabernacle Hill.
[6] Certain conditions increase the likelihood of dust devil formation. Flat barren terrain, desert or tarmac: Flat conditions increase the likelihood of the hot-air "fuel" being a near constant. Dusty or sandy conditions will cause particles to become caught up in the vortex, making the dust devil easily visible, but are not necessary for the ...
Lava Butte is a cinder cone in central Oregon, United States, just west of U.S. Route 97 between the towns of Bend, and Sunriver in Deschutes County.It is part of a system of small cinder cones on the northwest flank of Newberry Volcano, a massive shield volcano which rises to the southeast.
