Situated on a cliff 185 ft above the blue Pacific, the cylindrical white Point Vicente Lighthouse is crowned by a handsome lantern with cross-hatched windows. The 67 ft (20 m) concrete tower was first lit on April 14, 1926 and its original 3rd order Fresnel lens is still in use. Automated in 1971, the well preserved light station is open to the public the second Saturday of each month and is allowed to climb the tower's 74 steps. The lighthouse is located north of Terranea Resort, next to Point Vicente Interpretive Center, off Palos Verdes Drive in Rancho Palos Verdes, California.
Nikola Tesla was a Croatian scientist-inventor and electrical engineer known for his studies in the field of electromagnetism which contributed to the birth of commercial electricity. Tesla’s A.C. induction motor conceived in 1883 is widely used throughout the world in industry and household appliances. It started the industrial revolution at the turn of the century. Electricity today is generated transmitted and converted to mechanical power by means of his inventions. Tesla arrived in New York in 1886, became a naturalized citizen of the United States in 1891 and is considered one of the outstanding intellects of the world who paved the way for many of the technological developments of modern times. The 20¢ stamp issued on September 9, 1983 is part of a four-stamp series devoted to American inventors.
On June 28, 2009 the U.S. Postal Service issued a 79–cent definitive stamp, part of the well-known Scenic American Landscapes series, presenting Zion National Park, located in Utah, Southwestern United States. The park is known for its incredible deep canyons, high plateaus and striking rock towers and mesas. The stamp depicts a photograph showing layers of sedimentary rock that reflect the park’s geologic origins in the slick rock area on the east side of the park. Thank you, Lori.
