Thanks to Girl Scout Troop 357 in Lakewood—we have just such a thing today. On 9News 6 a.m. Troop Leader Leslee Randolph said the girls worked for months trying to convince Colorado lawmakers to make yule marble the official state rock.

Their work is paying off with a State Capitol ceremony involving Governor Owens.

Yule marble, which comes from the Yule quarry in Colorado, has been used in many buildings, including the Washington Monument and the Tomb of the Unknowns.

It also was used extensively throughout the Colorado State Capitol. For their work, the girls of Troop 357 earned geology and government badges. And now, a place in state history.
