The massive landslide in Glacier Bay National Park, Alaska, buried an entire valley in the park. The reason was because of a 3.4 magnitude earth quake. It effected tourists visiting the park by burying one of the valleys beneath the 11,750-foot Lituya Mountain. It was in the Fairweather Range about six miles from the border of British Columbia. It doesn't say that they did anything to fix it so I don't know how much the damage cost, but the picture looks like the mud didn't hit anything major so they might not have done anything to fix it.

Landslides

Definition: When some land off the side of a mountain weakens and gives way causing the land to "slide" down the mountain like an avalanche.

I think 4 was there first. Then number 2. After number two I think B split them because they're both broken. 5 could of came next  and then right after that, A. because of superposition, 6 would have to come next and then 1 last because the highest layer up is the newest.

"After watching the slideshow, speculate about why early geologists may have begun to suspect that the Earth was older than 6,000 years."

I think early geologists thought the Earth was older than 6,000 years because they saw rock formations and trenches that look like water was there to break away at the rocks. If the areas were small then maybe 6,000 years would be right but I don't think the water would completely disappear after only 6,000 years. 6,000 may sound like a big number but compared to the universe and space things it's a really short time. That's why scientists would think Earth's older than 6,000 years old.
