Varves are best developed near glaciers because they represent light colored layers of coarser material deposited in the summer when the streams issuing from glaciers have more energy to erode coarser material compared to the fine silts and clay of the winter months when there is very little flow and very little erosion.

The United States has a good amount of freshwater supply over most of the territory, because the American territory is ripe with lakes, rivers, streams, and groundwater.
The quality of these water sources varies from area to area, and many water bodies have been deeply polluted by human activity. However, the United States is a developed country with generally good water treatment facilities.
Notwithstanding, the United States faces two important challenges: one is the growing population of the country, which will put more pressure on freshwater sources in the future. The other one is that a few areas of the country are devoid of water supply sources, and they are among the fastest growing regions of the U.S (Nevada, Arizona, New Mexico). This poises a great challenge for U.S. authorities in the near future.
