  • Walk a short loop around Red Rock Canyon in Waterton Lakes National Park, Canadian Rockies, Alberta, Canada. In 1932, Waterton-Glacier International Peace Park joined Glacier National Park in Montana with Waterton. UNESCO honored Waterton-Glacier as a World Heritage Site (1995) containing two Biosphere Reserves (1976). Geology: Rocks in these parks are primarily sedimentary layers deposited in shallow seas over 1.6 billion to 800 million years ago. During the tectonic formation of the Rocky Mountains 170 million years ago, the Lewis Overthrust displaced these old rocks over newer Cretaceous age rocks.

  • Billion-year-old rock breaks into a jagged pattern in Glacier National Park, Montana. This image is permanently displayed on the glass of two large lightboxes measuring 19.6 by 8.4 meters (64.3 ft wide x 27.5 ft high) and 16.3 by 3.5 meters (53.6 ft wide x 11.6 ft high), which wrap corners of the following skyscraper constructed by Axiom Builders in June 2019: SODO Residences, 620 10 Ave SW, Calgary, Alberta, CANADA (on the Corner of 5th St and 10 Ave SW). Published in "Light Travel: Photography on the Go" book by Tom Dempsey 2009, 2010. Since 1932, Canada and USA have shared Waterton-Glacier International Peace Park, which UNESCO declared a World Heritage Site (1995) containing two Biosphere Reserves (1976). Rocks in the park are primarily sedimentary layers deposited in shallow seas over 1.6 billion to 800 million years ago. During the tectonic formation of the Rocky Mountains 170 million years ago, the Lewis Overthrust displaced these older sediments over newer Cretaceous age rocks.

  • A mountain goat surveys Hidden Lake in Glacier National Park, Montana, USA. The mountain goat (Oreamnos americanus, or Rocky Mountain Goat) is a large-hoofed mammal found only in North America. It is an even-toed ungulate in the family Bovidae, in subfamily Caprinae (goat-antelopes), in the Oreamnos genus, but is NOT a true "goat" (or Capra genus). Since 1932, Canada and USA have shared Waterton-Glacier International Peace Park, which UNESCO declared a World Heritage Site (1995) containing two Biosphere Reserves (1976). Rocks in the park are primarily sedimentary layers deposited in shallow seas over 1.6 billion to 800 million years ago.

  • A mountain goat rests at Hidden Lake by Bearhat Mountain in Glacier National Park, Montana, USA. The mountain goat (Oreamnos americanus, or Rocky Mountain Goat) is a large-hoofed mammal found only in North America. It is an even-toed ungulate in the family Bovidae, in subfamily Caprinae (goat-antelopes), in the Oreamnos genus, but is NOT a true "goat" (or Capra genus).

Rocks in the park are primarily sedimentary layers deposited in shallow seas over 1.6 billion to 800 million years ago. During the tectonic formation of the Rocky Mountains 170 million years ago, the Lewis Overthrust displaced these old rocks over newer Cretaceous age rocks. Glaciers carved spectacular U-shaped valleys and pyramidal peaks as recently as the Last Glacial Maximum (the last "Ice Age" 25,000 to 13,000 years ago). Of the 150 glaciers existing in the mid 1800s, only 25 active glaciers remain in the park as of 2010, and all may disappear as soon as 2020, say climate scientists.

Rocks in the park are primarily sedimentary layers deposited in shallow seas over 1.6 billion to 800 million years ago. During the tectonic formation of the Rocky Mountains 170 million years ago, the Lewis Overthrust displaced these old rocks over newer Cretaceous age rocks. Glaciers carved spectacular U-shaped valleys and pyramidal peaks as recently as the Last Glacial Maximum (the last "Ice Age" 25,000 to 13,000 years ago). Of the 150 glaciers existing in the mid 1800s, only 25 active glaciers remain in the park as of 2010, and all may disappear by 2020, say climate scientists.

  • Billion-year-old sedimentary rock erodes into orange patterns in Glacier National Park, Montana, USA. Rocks in the park are primarily sedimentary layers deposited in shallow seas over 1.6 billion to 800 million years ago. During the tectonic formation of the Rocky Mountains 170 million years ago, the Lewis Overthrust displaced these old rocks over newer Cretaceous age rocks. Since 1932, Canada and USA have shared Waterton-Glacier International Peace Park, which UNESCO declared a World Heritage Site (1995) containing two Biosphere Reserves (1976).

  • A mountain goat appears to smile at Hidden Lake in Glacier National Park, Montana, USA. The mountain goat (Oreamnos americanus, or Rocky Mountain Goat) is a large-hoofed mammal found only in North America. It is an even-toed ungulate in the family Bovidae, in subfamily Caprinae (goat-antelopes), in the Oreamnos genus, but is NOT a true "goat" (or Capra genus). Since 1932, Canada and USA have shared Waterton-Glacier International Peace Park, which UNESCO declared a World Heritage Site (1995) containing two Biosphere Reserves (1976).

  • Rising Wolf Mountain (9513 feet/2899 meters) and Sinopah Mountain (left) reflect in Pray Lake, in Glacier National Park, Montana, USA. Since 1932, Canada and USA have shared Waterton-Glacier International Peace Park, which UNESCO declared a World Heritage Site (1995) containing two Biosphere Reserves (1976). Rocks in the park are primarily sedimentary layers deposited in shallow seas over 1.6 billion to 800 million years ago. During the tectonic formation of the Rocky Mountains 170 million years ago, the Lewis Overthrust displaced these old rocks over newer Cretaceous age rocks. Glaciers carved spectacular U-shaped valleys and pyramidal peaks as recently as the Last Glacial Maximum (the last "Ice Age" 25,000 to 13,000 years ago). Of the 150 glaciers existing in the mid 1800s, only 25 active glaciers remain in the park as of 2010, and all may disappear by 2020, say climate scientists.
