What is the most common category of rock found in Alberta?
There are three classifications of sedimentary rocks and 90% of Alberta’s bedrock is of the sedimentary class (Mussieux and Nelson, 1998). Sedimentary rocks are fragments (or clasts) of other rocks compressed under pressure to form a new mix of rock such as sandstone, shale, or conglomerate.

How do I identify a rock that I found?
Possibilities include:
- Your state geological survey.
- A natural science museum.
- A college or university with a geology department.
- A rockshop.
- Members of a local Gem & Mineral club or Rockhunting club (many hobbyists are experts at identification)
- Vendors at a Gem & Mineral show.
Do hoodoos last forever?
Unfortunately hoodoos don’t last very long. The same processes that create hoodoos are equally aggressive and intent on their destruction. The average rate of erosion is calculated at 2-4 feet (. 6-1.3 m) every 100 years.
Why are hoodoos special to Alberta?
Drumheller’s hoodoos are one of Alberta’s most distinctive natural attractions. The stone caps contain nearly 40 per cent calcite cement, making them exceptional slow to erode. The hoodoos also have unique banding that shows the different stages of the earth’s formation.
How long does it take hoodoos to form?
Hoodoos form over millions of years of erosion in areas where a thick layer of soft rock is covered by a thin layer of hard rock. Over time, hoodoos form as a small cap of the hard layer protects a cone of softer rock underneath from erosion. Hoodoos can be a squat 5 feet (1.5 meters) tall or soar to 150 feet (45 m).
Can you climb the hoodoos?
Each hoodoo is a sandstone pillar resting on a thick base of shale that is capped by a large stone. Hoodoos are very fragile and can erode completely if their capstone is dislodged (in other words, no climbing allowed).
How did the Badlands form Alberta?
Many of Alberta’s badlands were initially formed as a result of rapid channel downcutting (erosion) by glacial meltwater during the retreat of the Laurentide ice sheet about 13,000 years ago in the late Wisconsinan period (see Glaciation).

Why is ammolite so rare?
Ammolite is actually one of the rarest gemstones in the world. This is because it is unique to a geological deposit known as the Bearpaw Formation. Just one area is known to yield gem-quality ammolite in commercial quantities, around the St. Mary River in Southern Alberta.
What is the rarest stone on the planet?
Painite
Painite : Not just the rarest gemstone, but also the rarest mineral on earth, Painite holds the Guinness World Record for it. After its discovery in the year 1951, there existed only 2 specimens of Painite for the next many decades. By the year 2004, there were less than 2 dozens known gemstones.

How do you tell if a rock is a meteorite?
Meteorites have several properties that help distinguish them from other rocks: Density: Meteorites are usually quite heavy for their size, since they contain metallic iron and dense minerals. Magnetic: Since most meteorites contain metallic iron, a magnet will often stick to them.
