Summary: This episode is about places that used to be and which are now covered up by something new. Yarrow Mamout was an unusual man in early America, but the black business leader's story was literally buried by buildings near Washington DC. In the 2000s, his story came to light. Also, the Los Angeles communities of La Loma, Palo Verde, and Bishop were often grouped together under the name Chavez Ravine. The people of these communities were uprooted, and now Dodger stadium stands where they once lived.
