Welcome to Wellington Beach The Wellington beach is a great place to walk, sunbathe, swim, picnic, canoe, kayak, launch your boat (docking facilities with electrical hook-ups and water available) and explore the interpretive signage along the boardwalk/pathway system. It is this signage which will aid you in answering the questions for this Earthcache. Since there is a boardwalk to all the required signposts, this Earthcache is fully wheelchair accessible. Location: Wellington Beach is accessed by way of of Beach Street in the village of Wellington. Free parking is available near GZ. The beach itself is actually a sandbar seperating Lake Ontario from West Lake. Background: Some 500 million years ago, during the Ordovician period of the Palaeozoic era, this area was flooded, and creatures living at the time became fossils as the limestone which now underlies much of Prince Edward County was formed. About a million years ago, glaciers ground over the county and modified the surface of both the island and the shoreline. These glaciers retreated about 12,700 years ago, creating this sandbar. A beach is a geological landform along the shoreline. It usually consists of loose particles which are composed of sand, gravel, and/or pebbles. Beaches form as waves deposit sand and other sediments and wind pushes these sediments inland, creating a beach and sometimes accompanying sand dunes. In this particular area, dunes have not yet formed, but can be experienced further to the south. For Earthcaches exploring the dunes, please see the following websites: GC2Q3WA GC5BAG9 The process of deposition can be accelerated by storms and other severe weather, causing a beach to grow or shrink depending on which direction the sediment is moving in. Logging Requirements: At waypoint 1 1. From the signboard, what is the length and width of this sandbar? 2. When was the channel excavated? Waypoint 2 1. When was the biggest recorded haul of fish from this beach? 2. How many fish were caught? Waypoint 3 1. Why was this beach dangerous for vessels on Lake Ontario? 2. How many known wrecks are there in this area? 3. Look around and tell us what has been created to decrease the hazardous conditions. (Two objects)
