High Falls Earth Cache
The High Falls (or Upper Falls) of the Genesee River in Rochester, New York is a fine waterfall located right in the middle of the city. This makes for a rather interesting urban setting for the waterfall view. High Falls, also known as Upper Falls, Genesee Falls, and the Great Falls of the Genesee, has a height of 96 feet and a crest width of 200 feet . The falls faces to the northwest, and the entire crest of the falls is overhung, resulting in a fantastic curtain of falling water. The falls is at its best in the spring, when the flow of the river is torrential. In the summer months the river volume can be rather low. The present river valley has been modified extensively from preglacial river valleys. The original river had two branches. The east branch has a larger preglacial valley. It was completely blocked by extensive terminal moraines just south of Dansville, so most of the upper section was diverted toward the Susquehanna River system. Now only a small creek flows in what is left of this large valley. The west branch, which was smaller, is now the Genesee River above Mount Morris.
That being said, the falls is certainly a good one.
The falls is visible from the pedestrian-only Pont du Rennes bridge in the Browns Race district. It is impossible to miss it. There is also a geocache nearby. GCYA2C
A waterfall is usually a geological formation resulting from water, often in the form of a stream, flowing over an erosion-resistant rock formation that forms a sudden break in elevation. Types of waterfalls are based on how the water falls or passes through it's course, how much water is flowing, the surface beneath it and the geological processes that created it (geomorphology). These all together form a waterfall's unique shape. Water as a whole, is a great tool when it comes to carving out this great planet we live on.
Types of Waterfalls...
Block: Water descends from a relatively wide stream or river.
Cascade: Water descends a series of rock steps.
Cataract: A large waterfall.
Fan: Water spreads horizontally as it descends while remaining in contact with bedrock.
Horsetail: Descending water maintains some contact with bedrock.
Plunge: Water descends vertically, losing contact with the bedrock surface.
Punchbowl: Water descends in a constricted form, then spreads out in a wider pool.
Segmented: Distinctly separate flows of water form as it descends.
Tiered: Water drops in a series of distinct steps or falls.
Multi-Step: A series of waterfalls one after another of roughly the same size each with its own sunken plunge pool.
From Wikipedia, the free encyclopedia
Preglacial: An ice age is a period of long-term reduction in the temperature of the Earth's surface and atmosphere, resulting in an expansion of continental ice sheets, polar ice sheets and alpine glaciers.
Moraine: refers to any glacially formed accumulation of unconsolidated glacial debris (soil and rock) which can occur in currently glaciated and formerly glaciated regions, such as those areas acted upon by a past ice age. This debris may have been plucked off the valley floor as a glacier advanced or fallen off the valley walls as a result of frost wedging. Moraines may be composed of silt like glacial flour to large boulders. The debris is typically angular. Moraines may be on the glacier’s surface or deposited as piles or sheets of debris where the glacier has melted. Moraines may also occur when glacier or iceberg transported rocks fall into the sea as the ice melts.
Waterfalls may also be artificial, and they are sometimes created as garden and landscape ornaments.
To log this earthcache you must post a picture of you with your GPS with the falls in the background and Email me the answers to the following questions...
1)Approximately how high are the falls?
2) Approximately how wide are the Falls?
3) Using the above types, Tell me What type of falls this is.
4)Give me your best guess in your own words as to how this waterfalls was formed.
Any Logs without the required picture posted with your log or without the emailed answers will be deleted. Pictures without a face will be deleted. Sorry for the inconvience but we know that a picture with your face can be took even if you are alone, a hand with a GPS does not prove you were there... Please do not post answers to your online log.
