This is the site of an old clay mining operation in Golden, Colorado. Soft clay horizons occurred between hard sandstone intervals of the Laramie Formation. The beds here are vertically oriented - structural tilting occurred during the Laramide Orogeny in the Tertiary. The Laramie Formation is a nonmarine, coastal plain to deltaic succession of mostly mixed siliciclastic sedimentary rocks - sandstones, siltstones, claystones, and coals.
After clay mining ceased, the site became a landfill for ash from coal burning operations. Landfill activity buried many dinosaur footprints preserved in the Laramie Formation sandstones. The locality is now a "fossil preserve" with dinosaur footprints, plant fossils, and other features that can be closely examined along trails. An odd-looking golf course makes up the rest of the old clay mine.

Clay Mining
Since 1877, five generations of the Parfet Family have mined clay from this area. Previously operated as the Parfet Clay Pit, the ceramic and brick industry used clay from this area primarily for bricks and sewer pipe. The Governor’s mansion, East and South High Schools in Denver, and the Jefferson County Hall of Justice in Golden were built from the distinctive tan bricks.
The clay, deposited in lakes and swamps 68 million years ago during the Late Cretaceous, is part of the Laramie Formation. Uplift of the modern day Rocky Mountains some 67-55 million years ago tilted the rock strata to their near vertical position. The clay layers were excavataed as trenches, leaving the vertical fins of sandstone visible today. Trace fossils such as dinosaur tracks and leaf impressions are visible on many of the remaining sandstone walls. The pits on either side of the trail contain fossil footprints that have yet to be detailed.
Logs, wedged horizontally between the sandstone walls, served as a warning device to miners. If the walls started to give way, the miners would hear the logs creak or “sing” and move to safety.

Clay Mining
Clay from the Fossil Trace Golf Course, previously operated as the Parfet Clay Pits, has been mined for the ceramic and brick industries since 1877 by five generations of the Parfet family. The predominant uses of this clay were for brick and sewer pipe. The tan brick was used to build the Governor’s mansion, East and South High Schools in Denver and the Jefferson County Hall of Justice in Golden. The clay was deposited in small ponds and depressions about 70 million years ago in the Late Cretaceous period and became part of the Laramie Formation. The rock strata were tilted vertical by the uplift of the modern day Rocky Mountains to the west approximately 60-65 million years ago. Clay layers were excavated as trenches, leaving vertical fins of sandstone, which contain trace fossils. The sandstone was originally sand which was deposited when adjacent streams overflowed their banks during flood events.

By the end of March 2021, nearly all of the structural steel work for the Chen Family Lower School was completed, including the roof decking on Section B in the middle of the complex and Section C (shown here) on the south end of the building. In May, construction crews will pour concrete flooring on the first and second floors, as well as continue interior welding in preparation for sectioning of halls, classrooms and other spaces. Interior drywalling is expected to start by late summer. (Photo by Scott Thien/ISI)
The cathedral is located in the Cathedral Hill neighbourhood of San Francisco, California. The present cathedral replaced one (1891-1962) of the same name. The cathedral was designed by local architects John Michael Lee, Paul A. Ryan and Angus McSweeney, collaborating renown architects Pier Luigi Nervi and Pietro Belluschi — at the time, the Dean of the School of Architecture at MIT.
Its saddle roof is composed of eight segments of hyperbolic paraboloids, in such a fashion that the bottom horizontal cross section of the roof is a square and the top cross section is a cross.
In 2017, Architecture Digest named it one of the 10 most beautiful churches in the United States.
Initial program and structural meshwork. The design is based around the idea of circulation and programmatic core, feeding outwards to the holding areas and jetways. Initially the structure condensed to support program volumes and walkways.
For their ENGS 71: Structural Analysis course, students designed and constructed a treehouse at Hanover's Storrs Pond Recreation Area.

The International Finance Centre (abbr. IFC, branded as "ifc") is an integrated commercial development on the waterfront of Hong Kong's Central District.
A prominent landmark on Hong Kong Island, IFC consists of two skyscrapers, the IFC Mall, and the 55-story Four Seasons Hotel Hong Kong. Tower 2 is the second tallest building in Hong Kong, behind the International Commerce Centre in West Kowloon. It is the fourth-tallest building in the Greater China region and the eighth-tallest office building in the world, based on structural heights; by roof height, only the Taipei 101, Shanghai World Financial Center, Willis Tower, International Commerce Centre and Burj Khalifa exceed it. It is of similar height to the former World Trade Center. The Airport Express Hong Kong Station is directly beneath it.

Electrical substations can be really cool looking with a dramatic sky behind. Stopped and took this on the way home from work one evening. Used the backlight setting on my Kodak Easy Share C875! Your comments on this photo would be greatly appreciated.
