Rokua UNESCO Global Geopark

What is Rokua Geopark and the Heritage of the Ice Age? Rokua Geopark is Finland’s first UNESCO Global Geopark. There are more than 160 Geoparks in the world, exploring natural and cultural heritage through education, research and tourism.

Rokua Geopark focuses on the heritage of the Ice Age. Over billions and thousands of years, the movement of bedrock and several ice ages have shaped the landscapes of Lake Oulujärvi, Rokua and the River Oulujoki. You can see the heritage of the Ice Age in high dunes, deep kettle holes, large mires, spectacular sandy shorelines and boreal forests carpeted with white lichen.

What’s ice?

Ice is a solid form of water.

It occurs when the tem+ perature drops below the freezing point.

0 °C 32 F When the temperature rises, ice melts. Ice is – found in the ice cover of natural waters, such as in the River Oulujoki, Rokua’s kettle holes and Lake Oulujärvi, and in the snow cover, atmosphere and glaciers. During the Ice Age, Rokua Geopark was covered by a glacier more than two kilometres thick.

Landscape puzzle How the bedrock and life developed

You could think of Rokua Geopark’s landscape as a puzzle. The oldest pieces may have been in the bedrock for billions of years, while the youngest pieces were formed in the bedrock and soil in the last 11,000 years. Grouped by birth and age, these geological pieces of landscape create a story of evolution that reveals how the area received its current features.

Rokua Geopark’s oldest gneiss rocks crystallised nearly 2,900 million years ago. The bedrock in Rokua Geopark was born long before dinosaurs, at a time when the only living organisms on Earth were bacteria.

1 square = 1 0 0 years How soil developed Over a million years, Finland was repeatedly under a slow-flowing continental ice sheet. The ice sheet transported boulders and created smooth, striated rock formations known as “roche mountonnées”. The melt water stream deposited sand from the Muhos formation into an esker. Moraine ridges were formed on the bottom and edge of the ice sheet, while melting ice blocks created kettle holes in eskers. Rokua Geopark emerged from under the ice sheet between 10,700 and 10,500 years ago. Lake Oulujärvi was cut off from the early Baltic Sea, called the Ancylus Lake, about 9,500 years ago.

1 sq u are = 100 years Soil development and stages of vegetation Wind carried fine-graided sand from sandy beaches, creating the dunes in Rokua. As a result of land uplift, the River Oulujoki began 9,500 years ago as an outlet for Lake Oulujärvi. In four thousand years, the land uplifted so much that the river channel reached Muhos near the current Pyhäkoski power plant. The tributaries and streams of the River Oulujoki carved deep valleys known as ravines into the sandy soils of the river valley. Peat formation began in wet depressions straight after the terrain exposed from water, and accelerated as climate cooled about 6,000 years ago. The development of channels and mires still continues.

Pyhäkoski’s Stone Age dwelling sites are about 6,00–5,000 years old. Some Bronze and Iron Age discoveries have also been made.

2

Tar and rapid shooting From the 16th century until the 1920s, tar was transported down the River Oulujoki from Kainuu by rowing boats. You can find many tar-burning pits in the area. From the 19th century until the 1940s, the rapids were a popular tourist destination

Old churches Kainuu’s first church in Manamansalo was burned down in the violent skirmishes of the Russo-Swedish War (1578-1581). Muhos Church was built in 1634, Utajärvi in 1762 and Säräisniemi in 1782.

Kalevala rune singers Folk healers and traditional storytellers, known as rune singers, lived in Ahmas from the 17th century until the 19th century. You can find their stories in Kalevala, the Finnish national epic.

Emperor’s Road The Emperor’s Road, or Keisarintie in Finnish, was built between the fortresses in Oulu and Kajaani from the 17th century onwards. Tsar of Russia, Emperor Alexander I, visited Lake Oulujärvi in 1819.

Time Travel Using modern virtual technology, you can discover how Rokua Geopark’s landscapes around Lake Oulujärvi, Rokua and the River Oulujoki have looked like through the ages. You can visit Rokua Geopark’s exhibitions and explore the unique Ice Age Heritage Story. Jump billions of years into the past and see the mountains as they were then, visit a continental ice sheet with a thickness of two kilometres, walk around a Stone Age village, and explore the sceneries of the early 20th century and today. With a VR headset and controller, you can get a realistic experience of the landscape around you, visit the surrounding area, watch how people lived their lives, view objects and perform tasks. The project has been designed by Rokua Geopark, Kajaani University of Applied Sciences, Geological Survey of Finland, the Museum and Science Centre Luuppi. The project has consulted scientists on geology, biology and human cultural history.
