regards,
No they did not bury the skeleton. They buried the site in order to keep anyone from doing anymore digging there.
From my profile page.
The site where Kennewick Man was discovered in July 1996 is overgrown with vegetation in July 1998, four months after the Army Corps of Engineers covered the area with dirt and burlap.

I live right across the Columbia River from this site. Scientists wanted to be able to study the area further, before the Army Corp of Engineers covered the site over. So our Congressman, Doc Hastings entered a bill to put a stop to the Army Corps covering of the site. The bill passed in the House and in the Senate, but before the vote could be recorded the Army Corp of Engineers (by someones directive) went ahead and covered the site with rocks, burlap, and vegetation so that no one will ever be able to go in and study the site
