This statue is ‘Stone of Hope,’ part of the Martin Luther King, Jr. Memorial that opened in 2011 in West Potomac Park, Washington, DC. The title of the 30-foot granite sculpture comes from a line in King"s ‘I Have A Dream’ speech: ‘Out of the mountain of despair, a stone of hope.’ Across the country today, volunteers will spend their day giving back in honor of Dr. King. His birthday was made a federal holiday in 1983, and in 1994 Congress designated the event as a national day of service, inviting citizens to observe the holiday by improving their communities.
