4. Dartmouth College Ecology tour traveled via fishing boat to Cocos Island, some 300 km from Costa Rica’s Pacific coast.Cocos Island National Park was designated a World by in 1997. In 2002, the World Heritage Site designation was extended to include an expanded marine zone of 1,997 km².Cocos Island is an oceanic island of both volcanic and tectonic origin. It is the only emergent island of the Cocos Plate, one of the minor tectonic plates

On the way you pass through several diverse climates and see a huge Variety of flora, from tropical to arctic tundra.

7. Welcome aboard one of the most popular train excursions in North America. This one day wilderness excursion will take you 114 miles north of Sault Ste. Marie, over towering trestles, alongside pristine northern lakes and rivers, and through the awesome granite rock formations and mixed forests of the Canadian Shield.

10. The island of Arran is a popular destination for geologists, who come to see intrusive igneous sills and dikes as well as sedimentary and metasedimentary rocks ranging in age from Precambrian to Mesozoic.

11. EdinboroughAbout 1 km from the city center, the remnants of the long extinct volcano of Arthur’s Seat rise from the low ground on whichEdinborough is built.

12. Hutton's Unconformity, Siccar PointFamous for Hutton's observations that provided evidence for geological evolution. Here, Silurian greywackes, laid down approximately 425 million years ago are underneath Devonian sandstone deposited approximately 345 million years ago

13. Hadrian’s WallThe Whin Sill is a tabular layer of igneous rock, or sill, in the northeast of England. The Romans certainly appreciated and exploited the geology. Emperor Hadrian chose the narrowest route across northern England for his Wall, and took advantage of the natural defenses of the crags between Walltown and Sewingshields. These crags mark the outcrop of the Whin Sill, one of the most important features of northern England geology.

The Daintree Rainforest and Great Barrier Reef - majestic and unsurpassed in biological significance.

23. Hypipamee National ParkMt Hypipamee crater is a diatreme formed by an explosive eruption of volcanic gases which blasted through solid granite. Angular blocks of granite as large as refrigerators can be found in the surrounding rainforest, giving testimony to the power of the explosion that hurled them there.

27. The Newfoundland StoryRocks on the Island of Newfoundland are divided into three zones - Western, Central and Eastern. The Western Zone has been part of North America for at least the last billion years (1000 million), but the other two zones are relative newcomers.Geological Subdivisions of Newfoundland.The bringing together of ancient oceans and continents has given Newfoundland three geological zones: the Western, Central and Eastern zones. Each of these zones has distinct rock types and geological histories.

28. Newfoundland preserves evidence of the closing of the Iapetus ocean, the collision of the continents and the resulting deformation.

29. Layered limestones and shales at Green Point, Gros Morne National Park.The rocks of the coastal terrace and cliffs at Green Point originated offshore in the Iapetus Ocean about 500 million years ago. These fossil-bearing limestones and shales were transported from about 100 km to the east of this site during the collision of ancient continents. Now they lie tipped at 115 degrees, just past the vertical. This is one of the rock sequences that geologists have studies in theirattempt to reconstruct the ancient continental margin of eastern North America.

30. The Mohorovicic Discontinuity, which reflects the different densities of the crust and the mantle, normally occurs at a depth of 35 km beneath the continents and about 10 km beneath the oceans. But here you can literally stand with one foot on the gabbro of the ocean crust and the other on the peridotite of the ocean mantle. It is because of this unusual sequence of rocks and other aspects of Gros Morne's geology and landscape that in 1988 Gros Morne was declared a UNESCO World Heritage Site..

32. 1994 – Indonesia: Bali, Lombok, East Java.Mount Batur (Gunung Batur) is an active volcano located at the center of two concentric calderas north west of Mount Agung, Bali, Indonesia. The south east side of the larger 10×13 km caldera contains a caldera lake. The inner 7.5-kilometer-wide caldera, which was formed during emplacement of the Bali (or Ubud) ignimbrite, has been dated at about 23,670 and 28,500 years ago

34. East JavaMount Bromo (Indonesian: Gunung Bromo), is an active volcano and part of the Tengger massif, in East Java, Indonesia. At 2,329 metres (7,641 ft) it is not the highest peak of the massif, but is the most well known. The massif area is one of the most visited tourist attractions in East Java, Indonesia.
