Final answer:
Moving towards the edge of the glacier in Glacier Bay, Alaska would lead to the proglacial area, while moving away from the edge would lead to the tundra biome.
Step-by-step explanation:
If you are standing in a location in Glacier Bay, Alaska that is dominated by Dryas, moving toward the edge of the glacier would most likely lead you to encounter the proglacial area. This area is characterized by rocks, gravel, and streams that are formed as the glacier melts and retreats. Moving in the opposite direction, away from the edge of the glacier, would lead you to encounter the tundra biome. This biome is characterized by low-growing vegetation, such as shrubs, mosses, and lichens, and is found in areas with harsh, cold climates.
