Mount Popa is a volcano 1518 metres (4981 feet) above sea level, and located in central Burma (Myanmar) about 50 km (31 mi) southeast of Bagan in the Pegu Range. It can be seen from the River Ayeyarwady (Irrawaddy) as far away as 60 km (37 mi) in clear weather. Mount Popa is perhaps best known for the nearby stunningly picturesque Popa Taungkalat monastery atop an outcrop. The Popa Taungkalat (Taung Kalat) Shrine is home to 37 Mahagiri Nats, or spirits. Statues depicting the Nats are at the base of the Shrine.
The main edifice of the volcano is composed of basalt and basaltic andesite lava flows, along with pyroclastic deposits and scoriaceous material, originating from strombolian eruptions which are thought to have made up the later stages of the volcano's growth. The volcano also contains a 1.6 km (0.99 mi) wide and 0.85 km (0.53 mi) deep caldera that is breached to the northwest and is thought to have formed due to failure of the volcano's slopes. A 3 km3 (0.72 cu mi) debris avalanche can be found to the north of the caldera's breach. It covers an area of 27 km2 (10 sq mi).
Southwest of Mount Popa is Taung Kalat (pedestal hill), sheer-sided volcanic plug, which rises 737 metres (2,417 ft) above the sea level. A Buddhist monastery is located at the summit of Taung Kalat. At one time, the Buddhist hermit U Khandi maintained the stairway of 777 steps to the summit of Taung Kalat. The Taung Kalat pedestal hill is sometimes itself called Mount Popa and given that Mount Popa is the name of the actual volcano that caused the creation of the volcanic plug, to avoid confusion, the volcano (with its crater blown open on one side) is generally called Taung Ma-gyi (mother hill). The volcanic crater itself is a mile in diameter.
From the top of Taung Kalat one can enjoy a panoramic view. One can see the ancient city of Bagan; behind it to the north, the massive solitary conical peak of Taung Ma-gyi rises like Mount Fuji in Japan. There is a big caldera, 610 metres (2,000 ft) wide and 914 metres (3,000 ft) in depth so that from different directions the mountain takes different forms with more than one peak. The surrounding areas are arid, but the Mt Popa area has over 200 springs and streams. It is therefore likened to an oasis in the desert-like dry central zone of Burma. This means the surrounding landscape is characterized by prickly bushes and stunted trees as opposed to the lush forests and rivers Burma is famous for. Plenty of trees, flowering plants and herbs grow due to the fertile soil from the volcanic ash. Prominent among the fauna are Macaque monkeys that have become a tourist attraction on Taung Kalat.
