Lampeter Pennsylvania USA Vertical Dial 545
A 32x64-inch cast stone vertical declining dial located 25 feet up a vertical column at the school's entrance. An EOT plaque is located below the dial.
 
 
Lancaster Pennsylvania USA Heliochronometer Dial 875
This 7.5 inch diameter heliochronometer was milled out of aluminum and set to the site latitude with a mounting plate. One heliochronometer arm has a sun illumination counter sunk hole 0.125 inch in diameter and on the other arm an engraved analemma for proper pointing offset to display civil time. Time marks are milled at 5 minute intervals, and a vernier is added (5 lines 4 minutes apart) so that time can be read to the nearest minute.
 
 
Langford British Columbia Canada Horizontal Dial 736
A cast bronze horizontal dial with thick bronze gnomon. Dial face shows hour lines and quarter-hour marks, and Roman hour numerals. Dial center includes a compass rose.
 
 
Lansing Michigan USA Vertical Dial 923
This is a vertical, east-declining sundial, 22 ft 6 in by 15 ft 10 in. The dial is constructed of 6061 aluminum alloy pieces electrostatically painted and bolted together,then mounted on a concrete block wall. The position of the gnomon, hour, solstice, and equinoctial lines are corrected for longitude to show time zone solar time. Stenciled hour line numbers are changed to display DST or EST at appropriate times of the year. Visitors can determine the correct time by referring to an Equation of Time display. During the year, the triangular gnomon tip casts its shadow on the declination lines of summer and winter solstices and equinoxes. This is the largest known vertical sundial in Michigan, and one of the largest in the United States.
 
 
Laramie Wyoming USA Horizontal Dial 159
An ornate 18 inch brass horizontal dial sits on a massive four-stone block pedestal. The dial has hour lines from 4am to 8pm, with hours in roman numerals. Time is graduated into 5-minute intervals. The 12-noon mark is 3/8 inch wide, allowing for the gnomon which is missing.
 
 
Las Cruces New Mexico USA Equatorial Dial 452
A large equatorial dial with steel gnomon. The massive dial is set simply on a set of tiered platforms. The inner tiers are rotated from the outer to align to the cardinal points. Elsie Raye Rigney Carr and Dr. Jesse Lawrence Carr gave the dial to the university in 1975 in memory of Raye Hines Rigney, Class of 1911.
 
 
Las Vegas Nevada USA Equatorial Dial 581
An equatorial dial with partial armillary rings made of stainless steel and brass with chrome trim. Dial face has hour lines for solar and longitude-corrected time. Inscribed with zodiacal symbols and dates. Dial is on private property but may be viewed from street.
 
 
Las Vegas Nevada USA Analemmatic Dial 634
An approximate 10 foot x 6 foot analemmatic dial on pavement sloping 3° to east. Hour lines and sunrise/sunset markers are brass inserts placed in pavement.
 
 
Lawrence Kansas USA Horizontal Dial 263
24x42x42' Concrete, stainless steel 17x2x21' The original limestone pointer and 'Eutin' flower were vandalized and replaced by stainless steel pointer and cast concrete flower.
 
 
League City Texas USA Equatorial Dial 678
A small ornate bronze equatorial dial with Roman numeral hours marked on inside of equatorial ring and Zodiacal signs on back side and also on base of dial. Dial is places on a flagstone and cement pedestal.
 
 
Leesburg Virginia USA Horizontal Dial 255
A small bronze horizontal dial on an 18 x 18 inch block of marble. Pedestal of Tennessee marble rests on the back of a carved tortoise. The sides of the square block capital are deeply carved with oak leaves and acorns. When the dial was seen in 1998, the dial was not aligned to north. Inspection of the dial face shows that it is not designed for the site latitude of 39? but higher in latitude, perhaps even 44?. It is thought the dial might have been purchased by Edith Eustis, wife of William Cocoran Eustis who owned the Oatlands estate for the first part of the 20th century. The maker's signature, "fecit," and a crown is spurious, since any legitimate dial maker would use name or initials. The date of 1717 is not convincing as it does not match the design of the dial. And, if purchased by Mrs. Eustis, it is probably not French or Italian, since the compass rose is delineated by the English letters for north, south, east and west.
 
 
Leisure City Florida USA Gnomonic Dial 814
Amid the many coral blocks (oolitic limestone rock) carved by eccentric Edward Leedskalnin (1887-1951) is a huge monolithic sundial. The gnomon is a horizontal L-shaped piece of iron fastened to the north corner of a limestone block about 8 feet high, weighing about 15 short-tons. Below the gnomon, carved into a second block of limestone is a portion of a hemisphere, smoothly filled in with concrete. Drawn on the hemisphere are analemma shaped hour and half-hour lines from 9am to 4pm. You can read the time with an accuracy of about two-minutes.
 
 
Lewisburg Pennsylvania USA Equatorial Dial 445
A large, ornate equatorial dial of brass sits outside the physics department building. The dial is approximately 8 feet across. Two pillars with brass balls support the dial plate. Two more pillars with ball support the gnomon wire. To add a flourish, the north most pillar and ball have a spread eagle holding the gnomon wire in its mouth. Unfortunately this beautiful dial is tarnished by age, with the analemmas for each hour barely visible on the dial plate. The gnomon wire, broken sometime in the past, is jury-rigged and tied together in the middle, resulting in a unkempt look to such a fine dial. A dark, round stone base, perhaps made of slate, approximately 8 foot in diameter supports the dial and pillars. The stone sits upon a 10 x 10 foot concrete pad.
 
 
Lexington Kentucky USA Horizontal Dial 606
A 14 foot diameter horizontal dial of granite, marble and limestone with shrubbery delineation in the center of a cul de sac street. The hour lines are shaped to include analemmas to correct for EOT and are adjusted for longitude and DST. The shadow of the tip of the gnomon traces declination lines for solstices and equinoxes.
 
 
Lincoln Nebraska USA Equatorial Dial 415
The Carroll Moore Memorial Dial is an equatorial disk dial built by Cold Spring Granite Co. The granite base weighs 6,270 lbs. and is about 6 ft. in diameter. The granite dial plate weighs 3,420 lbs. and is 5 ft. 8 in. in diameter. The stainless steel 5 inch gnomon rod weighs 200 lbs and is approximately 6 feet long from end to end through the equatorial disk. The dial face has hour marks for all 24 hour hours, placed for symmetrical effect rather than for practical time telling. The hours are rotated slightly to account for longitude so that 12:30 is the nearly vertical hour line. Web site has pictures of dial construction.
 
 
Little Rock Arkansas USA Vertical Dial 561
A 36-inch radius antiqued brass vertical dial declining 16.3° east of south mounted on exterior wall of private home. A separate bronze plaque shows EOT, dial coordinates and motto. Viewing of dial can be arranged by calling the owner.
 
 
Little Rock Arkansas USA Horizontal Dial 352
The Arkansas Sesquicentennial Sundial. Monumental horizontal dial in a 40 ft square patio made of stones from significant sites of the world. The gnomon is 17 feet high by 21.5 ft. long. The sundial won First Place in the International Bricklayers & Allied Craftsmens Union - presented every 5 years. It featured an outer adornment of brick contributed from over 70 nations. SUNDIAL WAS DESTROYED and no longer exists - Apr 2002
 
 
Littleton Colorado USA Equatorial Dial 511
The Littleton War sundial is an Erickson equatorial polar dial 6 feet in diameter made of light granite with a 3 inch steel rod as gnomon. Time is graduated by hour, half-hour, quarter hours and 5 minute marks over 24 hours. Noon is at the bottom, matching the 105 degree meridian. Designed to be read from the upper surface in Spring/Summer, from the under side in Fall/Winter. A plaque provides the Equation of Time to convert solar time to watch time. Dial is in a beautiful setting.
 
 
Lloydminster Alberta Canada Horizontal Dial 392
One of the largest horizontal dials in North America. Dial is 197 feet in diameter. It's location is on the 4th meridian at 110:0 west, a line that separates Alberta and Saskatchewan and divides the city of Lloydminister in half. (Lloydminister began as a single town in 1903, but was split in 1905 with the survey that created Alberta and Saskatchewan. The town remained divided until 1930 when by joint decree it was amalgamated back into a single city).
 
 
Logan Utah USA Analemmatic Dial 804
Work to design and make the Analemmatic Sundial was done by students of the sixth grade science class and teacher Eric Newell in 2005. The central walkway uses stepping stones sandblasted with the name of the months. John Westenskow's ceramics classes at Mount Logan Middle School made the time stones. Students surveyed and plotted the location of the stones and provided the physical labor to dig holes and pour cement.
