Earth Explorers: maps, rocks, dinosaurs, wildlife and bugs

Find your way with a map and compass, crack open the story of the rocks under our feet, meet the dinosaurs that lived here, and discover the wild animals and tiny creatures that share our coulees.

🗺 Map work

Read a map like a pro: scale, legends, contour lines and latitude. Make a play-dough contour map.

🧭 Compass and orienteering

“Red in the shed”, finding north by the sun and stars, and the sport of racing with a map.

⭐ Navigating by the stars

What a sextant is, how the North Star tells your latitude, and David Thompson, the man who gazes at stars. Make your own quadrant!

📍 Survey markers

Brass discs in the sidewalk, the mile-square checkerboard of our roads, and what W4M means.

💎 Rocks and minerals

The three kinds of rocks, the scratch test, and ammolite, Alberta’s own gemstone.

⛰ How our coulees were made

An ancient sea, the coal that built Lethbridge, Big Rock, and the floods that carved the coulees.

🦖 Dinosaurs of Alberta

Baby dinosaurs found near Warner, the Royal Tyrrell Museum in Drumheller, and the Calgary Zoo’s Prehistoric Park.

🦌 Wildlife of the coulees

Gophers, rattlesnakes, bull snakes, backyard deer, owls and more, and how to share the coulees safely.

🐞 Bugs and insects

Count the legs, watch a caterpillar change, and become a gentle bug explorer.

Explore outside, safely

  • Always tell an adult where you are going.
  • Stay back from coulee edges and river cutbanks.
  • Leave rocks, fossils and bugs where they belong in parks.
  • Check the weather first! Live conditions from our station.
