Tucked in a shallow valley in northeastern Pennsylvania is a mysterious geologic feature: 16 acres of sandstone boulders. Science Friday took a trip to Hickory Run State Park's "boulder field" and spoke with Megan Taylor, environmental education specialist, about why the rocks collected there. Could you find any place close by that you could find this many rocks in one place? What do you think about this area how did it form?
Field of Rocks
We're not sure if we know where there are that many rocks, but we have seen some smaller versions of rock fields. We found out that the boulders were formed by freezing and melting ice inside of bedrock.
ReplyDeleteWe also found that the boulders were formed by ice weathering.
DeleteThere are lots of rocks like that at red river gorge, they are not as big but they are still a rock field. The boulders were formed from ice weathering inside of the bedrock.
ReplyDeleteThis rock field formed when glaciers moved near the area and the melt-water froze then melted again, inside rock cracks to break them into smaller pieces. I don't know of any other place where you can find this many rocks all together, but there are usually a lot of rocks along the shores of rivers.
ReplyDeletelegos ist good
ReplyDeleteI would say North America. The climate got colder until a glacier occured in Canada as ice spread through almost half of the United States.-Dominic Deutsch
