White House - South Lawn Traditional Cache

The South Lawn at the White House in Washington, DC, is located directly south of the mansion, and is bordered on the east by East Executive Drive and the Treasury Building, and on the west by West Executive Drive and the Old Executive Office Building, and along its curved southern perimeter by South Executive Drive and a large circular public lawn called The Ellipse.

When the White House was first occupied in 1800 the site of the South Lawn was an open meadow gradually descending to a large marsh, the Tiber Creek, and Potomac River beyond.

Pierre-Charles L'Enfant's 1793 plan of the city of Washington, indicates a setting of terraced formal gardens descending to Tiber Creek. Later in 1850, landscape designer Andrew Jackson Davis attempted to soften the geometry of the L'Enfant plan, incorporating a semicircular southern boundary and meandering paths. Andrew Jackson Davis's changes included enlarging the South Lawn, creating a large circular lawn he termed the "Parade or President's Park" and bordered by densely planted shrubs and trees.

During the administration of Ulysses S. Grant the marsh to the south was drained, and the South Lawn received additional grading and 8 to 10 feet of fill to make the descent to the Potomac more gradual.

During the first administrations of Rutherford B. Hayes and Grover Cleveland the U.S. Army Corps of Engineers were engaged to reconfigure the South Lawn, creating the current boundaries much as they presently are.

You are looking for a 35mm film canister on Fairoak Lane, Whitehouse Industrial Estate, Runcorn - probably not quite as pretty as Washington.
