THE POPOCATEPETL BY ROBERT JENKINS ONDERDONK

The Popocatépetl (5,426 m -17,802 ft)  
Mexico

Painted in 1911
The mountain 
Popocatépetl  (5,426 m (17,802 ft) is an active volcano, located in the states of Puebla, Mexico, and Morelos, in Central Mexico, and lies in the eastern half of the Trans-Mexican volcanic belt.  The name Popocatépetl comes from the Nahuatl words popōca  (it smokes) and tepētl  (mountain), meaning Smoking Mountain. It is the second highest peak in Mexico, after Citlaltépetl (Pico de Orizaba) at 5,636 m (18,491 ft).
It is linked to the Iztaccihuatl volcano to the north by the high saddle known as the Paso de Cortés.
Popocatépetl is 70 km (43 mi) southeast of Mexico City, from where it can be seen regularly, depending on atmospheric conditions. Until recently, the volcano was one of three tall peaks in Mexico to contain glaciers, the others being Iztaccihuatl and Pico de Orizaba. In the 1990s, the glaciers such as Glaciar Norte (North Glacier) greatly decreased in size, partly due to warmer temperatures but largely due to increased volcanic activity.  By early 2001, Popocatépetl's glaciers were gone; ice remained on the volcano, but no longer displayed the characteristic features of glaciers such as crevasses.
Magma erupting from Popocatépetl has historically been predominantly andesitic, but it has also erupted large volumes of dacite. Magma produced in the current cycle of activity tends to be a mixture of the two.
Climbing route 
The first ascent was made by ameridian Tecuanipas in 1289. Nowadays the easiest way to reach the top is via the north face. It begins at Tlamacas Lodge located at 3947 meters above sea level and accessible from the neck separating the Popocatepetl of Ixtaccihuatl via a paved road. The trail, which passes through Las Cruces and crosses snowfields and glaciers, measuring nearly five kilometers long with a climb of 1453 mètres. The best time to climb is winter and early spring, especially from  December to  April. The first mountain ski descent was conducted by Francisco Gonzalez Rul and Eduardo de Maria y Campos 1947.
Eruptive history 
Popocatépetl is the most active volcano in Mexico, having had more than 15 major eruptions since the arrival of the Spanish in 1519. A major eruption occurred in 1947.
- On December 21, 1994, the volcano spewed gas and ash which was carried as far as 25 km (16 mi) away by prevailing winds. The activity prompted the evacuation of nearby towns and scientists to begin monitoring for an eruption.
- In December 2000, tens of thousands of people were evacuated by the government based on the warnings of scientists. The volcano then made its largest display in 1,200 years.
- On December 25, 2005, the volcano's crater produced an explosion which ejected a large column of smoke and ash about 3 km (1.9 mi) into the atmosphere and expulsion of lava.
- In January and February 2012, scientists observed increased volcanic activity at Popocatépetl. On January 25, 2012, an ash explosion occurred on the mountain causing much dust and ash to contaminate the atmosphere around it.
- On April 19, 2012, there were reports of superheated rock fragments being hurled into the air by the volcano. Ash and water vapor plumes were reported 15 times over 24 hours.
- On Wednesday May 8, 2013, at 7:28 pm local time, Popocatépetl erupted again with a high amplitude tremor that lasted and was recorded for 3.5 hours. It began with plumes of ash that rose 3 km into the air and began drifting W at first, but later began to drift ESE covering areas of the villages of San Juan Tianguismanalco, San Pedro Benito Juárez and the City of Puebla in smoke and ash. Explosions from the volcano itself subsequently ejected fragments of fiery volcanic rock to distances of 700 m from the crater.
- On July 4, 2013, due to several eruptions of steam and ash for at least 24 hours, at least six U.S. airlines canceled more than 40 flights into and out of Mexico City and Toluca airports that day.
- During 27 August–September 2014, CENAPRED reported explosions accompanied by steam-and-gas emissions with minor ash and ash plumes that rose 800-3,000 m above Popocatépetl’s crater and drifted W, SW, and WSW. On most nights incandescence was observed, increasing during times with larger emissions.
- On 1 September partial visibility due to cloud cover was reported.
- On 29 and 31 August the Washington VAAC reported discrete ash emissions.
- On January 7, 2015, CENAPRED reported that ash from recent explosions coats the snow on the volcano's upper slopes.
- On March 28, 2016, an ash column 2,000 metres high was released, prompting the establishment of a 12-kilometer “security ring” around the summit.
- On 3 April 2016, Popocatépetl erupted, spewing lava, ash and rock.

The painter 
Robert Jenkins Onderdonk  was an American painter and art teacher, born in Catonsville, Maryland.  IT is considered as an Aimportant artist in the first stage of Texas art. Robert Jenkins Onderdonk studied art at the National Academy of Design and the Art Students League of New York in the 1870s. Among his teachers were William Merritt Chase[3] and James Carroll Beckwith.
R. J. Onderdonk went to Texas in 1878  and married Emily Gould in 1881 and they had three children. He hoped to execute portraits for rich Texas citizens and make enough money to travel to Europe. He eventually stayed in Texas for thirty-eight years, where he painted and taught. In San Antonio, he founded an art association for women painters, the Van Dyck club, which later became the San Antonio Arts League; his daughter Eleanor was an important member and organizer.  In 1893 in Dallas, he co-founded the Art Students League of Dallas, pupils of which displayed their paintings each year at the State Fair of Texas, in Dallas.
Onderdonk's masterpiece, the 1903 painting Fall of the Alamo, was displayed at the 1904 Louisiana Purchase Exposition in St. Louis, and is now held in the Texas State Archives. Occupying central position in the painting is Davy Crockett, a depiction reproduced countless times in print; Crockett is portrayed in iconic style, "swinging his flintlock over his head to club the Mexicans advancing through a hanging cloud of gun smoke."  According to Fisk's A History of Texas Artists, he would have been ranked one of America's finest artists if he had spent more time painting rather than teaching.
