Earthly Musings – My Travel and Geology Blog: Around the World in 24 Days – A Story of Stone


After flying around the globe and stopping at world-class destinations, I recognized that that the one connecting “fabric” that weaves these varied locations together was stone. Whether it be the chiseled Mesozoic sandstone of Angkor Wat, or the Neoproterozoic marble of the Taj Mahal, the Archean granite popping upon the Serengeti plain, or Eocene limestone at Egypt’s temples and tombs, stone is the most elemental material – shaping structures, allowing civilization to advance. Barely anyone came on this exotic trip to learn about stone, yet nearly every stop was in one way or another shaped by it. I pick up this whirlwind of a story in Cambodia and its stone temples.

Cambodia – Siem Reap

Half way around the world in Southeast Asia (but much father away in terms of culture, economics and cuisine) is the temple complex at Angkor Wat. The approach city is Siem Reap with over one million  inhabitants. It is a lively city near to Angkor Wat and Tonle Sap, the largest lake in Southeast Asia.

Angkor Wat and Angkor Thom

Angkor Wat was constructed in the 12th century as a religious complex by King Suryavarman II. It covers over 400 acres and is the world’s largest religious complex. It took twenty-eight years to build (from 1122 to 1150 CE) and the stone for the complex was quarried from the Kulun Mountains 25 miles away. The rocks were transported by rafts in canals and oxen carts over roads to the site (see the 2nd photo below). The monument contains between 5 and 10 million blocks of stone, using far greater amounts than all of the Egyptian pyramids combined. Its outer wall measures 1 kilometer (0.62 miles) long by 4/5ths of a kilometer wide (one half mile). It is a truly stunning monument to the Khmer dynasty.

Tonle Sap is a natural lake in Cambodia that rises and falls over 10 meters (33 ft.) throughout the year. In the dry season when I visited, the lake is low and water flows from the lake, down the Tonle Sap river to the Mekong River. When the Mekong River floods in the monsoon season, it overflows its banks, spilling into the Tonle Sap river which subsequently fills Tonle Sap (Khmer for great lake or fresh river). See the Wikipedia page here for more graphics and information. If you note the hill in the photo below, I was quite taken by this feature as we approached the lake from Siem Reap. Out of nowhere, upon a vast lowland plain, a hill rose up on the shore of the lake. How did that happen? It is an erosional remnant on the plain, with a Khmer temple on top of it.
