Transcript of North Moraine Hill Glacier

The Helm Glacier



It is important to use more than one source for this kind of research because you can get more of an insight, and gain valid information. You can also verify the information and make sure it is correct. With more than one source you are able to see which is reliable and which is not. Some sources may not have as much information as another and may even have false information so it is best to use more than one source.
The Helm glacier is located in Garibaldi Provincial park in British Columbia. At it's LIA maximum the glacier used to cover a total area of 16.2km but now very little is left of it. This being because the Helm glacier has gone through massive recessions throughout years. It has been predicted that by the year 2050, the Helm glacier will no longer exist due to the extreme recession. Since 1928 the retreating of the glacier has been constant. The entire west part of the glacier has become small cirque glaciers after disintegrating.
In order for a glacier to advance, you would need the snow to add to the glacier and also freeze which would cause the glacier to advance. A huge impact would be the temperature or weather. The colder, the less chance of the glacier retreating and more snowfall.
Information Summary
As glaciers retreat, the volume of water that the region usually receives will definitely rise and there would be an increase in the amount of water as the glacier is melting. The sea level would also rise and the melting of the glacier may end up flooding the rivers and streams.
As a conclusion, the Helm glacier is definitely retreating more as opposed to advancing. And because of this it may no longer exist in the future. Which in my opinion, is predictable considering for many years it has been retreating continuously.
Question: By how much has the front edge of the glacier that you are researching changed (advanced or retreated) in the past century?
The terminus of the glacier has retreated about 1.4 km over the past century.
Question: As a glacier retreats, what will happen to the volume of melting water that a mountainous region normally receives?
Question B: How will this affect the mountain streams and rivers downstream?
Question: Think back to how a glacier is formed. What factor could contribute to a glacier advancing instead of retreating?
Glacier A 's terminus has changed 1300 m in the past century while Glacier B's terminus has changed 1300 m over the past century.
Question: Why is it important to use more than one source when doing this kind of research?
As the melting water will add to the streams and rivers, it could be enough to be able to cause a flood because of the high amount of water. It may also end up being hazardous to the area it is in. But if the glacier melts entirely, there would be a shortage of the water supply. Also, the sea level would rise.
