Fossil Collecting

This area features some of the best Devonian Era fossils in North America! Fossil deposits date back to more than 350 million years ago – before the dinosaurs roamed the earth. 

The erosive power of Rock Glen Falls and the Ausable River regularly release new fossils from their geological formations. The most commonly found fossils are brachiopods, horn corals and crinoid stems. 

Fossil Finding Etiquette

Each visitor is permitted to collect one fossil only to take home with them. 
Digging for fossils or the use of tools of any kind to extract fossils is strictly prohibited. 

Picnicking 

Two picnic pavilions can be reserved for groups or family reunions or weddings. To book one of the pavilions please call 519-828-3071 from May to October and 519-235-2610 in the off-season. 

Fishing

Fishing is permitted in the Ausable River only. Fishing is prohibited in the Hobbs-McKenzie Drain due to high volume of visitors. Fishing is permitted in compliance with applicable legislation. Outdoor Cards and Fishing Licences can be purchased from Service Ontario and other licence issuers. Please release any fish caught out of season. 

A number of native species are found in the Ausable River.

Geocaching

Geocaching is a worldwide game of hide and seek that uses GPS (Global Positioning System) technology to help people find hidden treasures called ‘caches.’

There are multiple Earthcaches at Rock Glen Conservation Area. Caches are of different sized waterproof containers and are hidden in a safe spot close to trails. They often contain a logbook and simple treasures like coins or toys inside. If you find a camouflaged cache by accident, have a look and put it back in the place you found it for others to enjoy.

Visit geocaching.com to find and download coordinates and clues to find these ‘treasures’ at the Morrison Dam Conservation Area.

Be aware of the following to help you enjoy your visit. 

Poison Ivy

Poison Ivy is a common, native plant in the Ausable Bayfield Conservation Authority watershed. 
‘Leaves of three, let it be. Berries white, take flight.’ Leaves may either have smooth edges or a few coarse teeth and may appear shiny. If you come into contact with Poison Ivy wash the affected area with hot soap and water as soon as possible, launder clothes in hot water. 
Habitat: Open woods, fields and roadsides, disturbed areas.

Giant Hogweed

Giant Hogweed is an invasive, non-native plant introduced from Asia. It has large, flat-topped to slightly dome-shaped flower (similar to Queen Anne’s Lace/Wild Carrot) and seed head and a bumpy or bristly stem. It can grow up to five metres in height. Skin contact with Giant Hogweed sap may cause severe skin rashes when exposed to sunlight.

Habitat: Roadsides, streambanks, waste areas, yards

Stinging Nettle

Stinging Nettle is from between half a metre in height to three metres tall. Stems and leaves are covered with short, stinging hairs which can cause irritation and inflammation if touched with bare skin. Flowers are in clusters with separate flowers attached by short stalks along a central stem about 1-7 centimetres long.

Ticks

Ticks are present in the Ausable Bayfield Conservation Authority watershed. 

  • Wear light-coloured clothing, so it’s easier to see ticks
  • Wear closed-toed shoes
  • Wear long-sleeved shirts
  • Wear long pants, tucked into your socks
  • Use insect repellent containing DEET
  • After outdoor activity put your clothes in the dryer

Check yourself and your children:

  • Behind your knees
  • On your head
  • In your belly button
  • In your groin area
  • In your underarm area
  • On the back of your body – use a mirror, or ask someone to check for you
  • It’s a good idea to have a shower as soon as you can to wash off any ticks.

If you discover a tick on your body remove it, place the tick in a secure container and contact your local public health unit 

Directions for removal can be found here:

Why should I visit?

Rock Glen Conservation Area is a unique island of nature within the Ausable Bayfield watershed jurisdiction.

Hours of operation: 

During daylight hours, the park is open for walking trails and visiting waterfalls year-round, weather permitting.

Museum

The park is home to the Arkona Lions Museum and Information Centre which houses an impressive collection of Devonian Era fossils, minerals, and artifacts found in the local area. There are stairs, boardwalks and bridge allowing visitors to safely explore the steep sides of the glen and the 10.7-metre high waterfall just upstream of the Ausable River.

Visitors and amateur archaelogists from all parts of North America have found many fossils in the exposed beds dating back 350 million years. Scientific names for these ancient treasures include crinoids, brachiopods, and trilobites.

The story of civilization around Rock Glen dates back to the time when the Paleo or Early indigenous peoples utilized the nearby hills to hunt the barren ground caribou some 10,000 years ago. Succeeding the Paleo age were the Archaic people who had adapted to a much milder climate some 6,000 years ago. The museum displays "fluted points" associated with the Paleo age and many "cache" blades from the Archaic indigenous peoples.

Accessible trails allow all visitors to see the park highlights including the scenic lookouts, museum and picnic areas.

This is a growing destination for weddings. #RockGlenWedding
