This cache was placed by the instructor of the SCUBA rangers program, in a popular diving area of West Hawk Lake.
You are looking for a black and yellow toolbox covered with yellow reflective tape. The cache contains a writing slate which can be used underwater and some swag.
It is placed at a depth of approximately 6 meters.
Congratulations to grnbrg for being FTF on the first SCUBA cache in Manitoba
West Hawk Lake is one of the most popular sport diving sites in Manitoba. It is known for it's tremendous maximum depth. The West Hawk Lake basin is in fact a metorite impact structure.
The lake today covers a total area of 3,685 acres, with a maximum length and width of 7.2 kilometers and 4.8 kilometers respectively. The maximum depth of the lake is approximately 110 meters in the sediment-water interface. The lake basin was formed approximately 150 million years ago, during a period of geoological time known as the Jurassic Period, by the impact of a meteorite. The meteorite itself was approximately 150 meters in diameter and was probably composed of iron. The tremendous explosion force of the impact has been estimated as being equivalent to that of 25 Megaton blast.
The resulting crater was subsequently eroded and modified by the scouring action of glacial ice, which retreated from South-Eastern Manitoba approximately 11,000 years ago. Meltwater from the retreating ice filled the crater forming what we now know as West Hawk Lake.
Remember, West Hawk Lake is often dark and ALWAYS cold; weather conditions can change water conditions dramatically.
To ensure a safe and enjoyable dive, it is suggested that the diver observe the following precautions:
- 1. Always mark your dive site with a diver down flag.
- 2. Be alert for boat traffic when surfacing and snorkelling.
- 3. Never dive alone and always do a buddy check before descending.
- 4. After a long snorkel, rest at the surface prior to descent.
- 5. Do not dive beyond your comfort zone.
- 6. Watch depth and bottom time carefully.
- 7. Practice good buoyancy control. Much of the bottom the lake is silty. Bottom floundering can drastically reduce visibility creating a hazard for you and for those following.
