JOAN CARTAN-HANSEN, HOST:

3
00:00:06,000 --> 00:00:07,333
Archaeologists could be

4
00:00:07,333 --> 00:00:08,766
described as detectives who

5
00:00:08,766 --> 00:00:10,866
attempt to reconstruct the past.

6
00:00:10,866 --> 00:00:11,966
Let's find out how

7
00:00:11,966 --> 00:00:13,500
archaeologists study U.S.

8
00:00:13,500 --> 00:00:14,800
history.

9
00:00:14,800 --> 00:00:16,166
Jamestown became the first

10
00:00:16,166 --> 00:00:17,666
permanent English settlement in

11
00:00:17,666 --> 00:00:19,333
North America in 1607.

12
00:00:19,333 --> 00:00:20,666
In the first years, residents

13
00:00:20,666 --> 00:00:21,900
struggled and nearly died out

14
00:00:21,900 --> 00:00:23,400
because of starvation and

15
00:00:23,400 --> 00:00:24,300
disease.

16
00:00:24,300 --> 00:00:26,433
By 1699, Jamestown was no longer

17
00:00:26,433 --> 00:00:28,566
a town, but remains an important

18
00:00:28,566 --> 00:00:29,966
historical site.

19
00:00:29,966 --> 00:00:31,633
Archaeologists today study how

20
00:00:31,633 --> 00:00:33,100
those first settlers lived and

21
00:00:33,100 --> 00:00:35,233
died; as well as the histories

22
00:00:35,233 --> 00:00:36,900
of the ancient peoples who lived

23
00:00:36,900 --> 00:00:38,266
in the area.

24
00:00:38,266 --> 00:00:39,533
And NASA is providing

25
00:00:39,533 --> 00:00:40,833
specialized equipment to help

26
00:00:40,833 --> 00:00:42,300
scan and protect artifacts.

27
00:00:42,300 --> 00:00:43,733
Archaeologists studying the

28
00:00:43,733 --> 00:00:45,266
Civil War use some high-tech

29
00:00:45,266 --> 00:00:46,400
gear too.

30
00:00:46,400 --> 00:00:47,733
Scientists at the Chickamauga

31
00:00:47,733 --> 00:00:49,066
and Chattanooga National

32
00:00:49,066 --> 00:00:50,233
Military Park are using

33
00:00:50,233 --> 00:00:51,866
ground-penetrating radar to find

34
00:00:51,866 --> 00:00:53,633
possible human remains.

35
00:00:53,633 --> 00:00:55,100
The science of archaeology plays

36
00:00:55,100 --> 00:00:56,533
an important role in helping us

37
00:00:56,533 --> 00:00:58,600
understand history.

38
00:00:58,600 --> 00:00:59,933
