Monument in Alexandria, Virginia to sisters Emily and Mary Edmonson, who attempted to escape from slavery in Washington, DC along with 75 other fugitive slaves aboard the Pearl in 1848. Recaptured, abolitionists contributed funds to purchase the sisters' freedom. Sculptor Erik Blome completed the monument in 2010. 

Monument commemorating Oberlin College's ties to the Underground Railroad, designed by Oberlin College senior Cameron Armstrong and completed in 1977. Many Oberlin faculty and students were involved in the 1858 rescue of fugitive slave John Price. 

Monument depicting the rescue of fugitive slave Jerry Henry on October 1, 1851 in Syracuse, New York. Black and white abolitionists stormed a federal hearing room and rescued Henry from proceedings under the 1850 Fugitive Slave Act, enabling Henry to make his way to Canada. 

Abolitionists gathered at Cazenovia, New York on August 21-22, 1850 to protest the proposed new Fugitive Slave Act then being debated in Congress. Frederick Douglass (seated) and Gerrit Smith (standing, behind table) headlined the gathering. Sisters Emily and Mary Edmonson (standing, wearing plaid shaws, on either side of Douglass) had gained fame in abolitionist circles for their involvement in the attempted mass escape from Washington, DC aboard the Pearl two years earlier. After that escape attempt failed, abolitionists had raised the money to purchase their freedom. Photograph by Ezra Greenleaf Weld.
