Look under Reports (http://www.glacierresearch.com/) at the slide presentation titled:
Monitoring Tidewater Terminus Dynamics Using Laser Ranging and Fixed Photography: Hubbard Glacier, Southeast Alaska
It definitely refers to ice accumulation in the glacier. It is not global warming that is causing the glacier to flow faster. It is ice accumulation.
1. The first step in the scientific method is to ask a question that you will do the experiment to solve.
2. The next step is to gather information, which you will use to make the hypothesis that Global Warming is the cause of the problem. You predict what you have already observed and attribute this effect to global climate change.
3. Next, you do the experiment, organize data to support your conclusion, etc.
4. After that, you state your conclusion, in which you answer your question and confirm that your hypothesis is correct - Global Warming is the problem.
5. Lastly, you report the results so that other people may admire your results as well as get the knowledge that you created before doing the experiment.
Bingo!!! WE HAVE A WINNER!

And gravity? Aren’t there some 18,000+ ft peaks in that area?
