This Earthcache will take you to two locations: the first is the shoreline of ancient Lake Iroquois and the second is the shoreline of its offspring, Lake Ontario. You will have to do some measurements to find the difference in altitudes of the two shores and also the distance between the two shores.
When Toronto was first settled, Front Street was on the shores of Lake Ontario. Starting in the 1850’s, millions of tonnes of fill were dumped into the harbour to provide increased land for industry and shipping, resulting in close to a one kilometre extension of today's shoreline south of Queen's Quay. Today, this land has many uses, including recreation and high rise condos and hotels.
However, if we travel back in time to 12 000 years ago, the present Front Street would have been underwater too – Glacial Lake Iroquois (the Ice Age predecessor of Lake Ontario) extended farther north to the coordinates listed.
This is a 2-stage Earthcache. To log your find:
Stage 1:
1] Go to the posted coordinates. At these coordinates, you will find a plaque at the bottom of the steepest part of the old Lake Iroquois bluffs. This plaque explains a bit of the history of Toronto’s shoreline. OPTIONAL: Post a photo of yourself OR your GPS somewhere on the steps facing toward the lake in your log for this cache.
2] Climb to the top of the steps and check the altitude at the top of the hill. Save this measurement for Stage 2.
Stage 2:
1] Travel due south from this location until you reach Lake Ontario. OPTIONAL: Add to your log posting a photo of yourself OR your GPS, again facing the lake, somewhere as close as you can get to the present shoreline and as close as you can get to the same line of longitude as in the posted coordinates – email these coordinates, along with the distance between the old and new shoreline, to Willipan.
2] Measure the altitude at the present shoreline of Lake Ontario – email Willipan the difference between the two altitudes you measured.
