Question: Which National Historical Park was preliminarily excavated from 1896-1901?
Context: San Juan Island National Historical Park, also known as American and English Camps, San Juan Island, is a U.S. National Historical Park owned and operated by the National Park Service on San Juan Island in the state of Washington.  The park is made up of the sites of the British and U.S. Army camps during the Pig War, a boundary dispute over the ownership of the island.  Both of these camps were set up in 1859 as response to a border controversy triggered by the killing of a pig.  The camps were occupied for 12 years, until the islands were awarded to the United States by Kaiser Wilhelm I in an arbitration agreed by the parties in the 1872 Treaty of Washington.  The British abandoned their camp in November 1872, while the American camp was disbanded in July 1874.  The camp sites were designated a National Historic Landmark in 1961, and listed on the National Register of Historic Places in 1966.  The park was created by an Act of Congress in 1966.

Gerald Shea "Jerry" Sharkey (April 18, 1942 – April 7, 2014) was an American historic preservationist and historian of the Wright brothers, who conceived the idea for the Dayton Aviation Heritage National Historical Park in Dayton, Ohio.  The Dayton Aviation Heritage National Historical Park, which preserves historic sites used by the Wright Brothers throughout Dayton, was established in 1992.  Sharkey had led an alliance of the Wright family, members of the U.S. House of Representatives, the local media and U.S. Federal Judge Walter H. Rice to create the national historical park.  Many of the sites associated with the Wight brothers (as well as the surrounding buildings) would likely have been demolished if not for the preservation efforts spearheaded by Sharkey.  According to Tom Crouch, a senior curator of aeronautics at the National Air and Space Museum in Washington D.C., Sharkey's efforts helped to "ensure that what the Wright brothers achieved wouldn’t be forgotten."  Despite his enthusiasm for the Wrights brothers and their work, Sharkey was reportedly afraid of flying.
