Although it hasn’t seen a train in over 46 years, the Portland Traction Company steel bridge over the Clackamas River at Gladstone, Oregon is likely seeing its last days.
Heavy rains recently have washed out the footing under the south pillar and the south end of the bridge is currently collapsing into the river. While the former Row has since been sold to local governments as part of a deal to create a rails to trail, the bridge was never transferred and is still owned by the Union Pacific. The Portland Traction Company was a joint owned railroad by the UP and SP, hence why the UP still owns the bridge today. …
This is the dramatic moment a stretch of grass-topped cliff toppled into the sea in a cloud of rubble and dust after the winter’s savage storms caused seven years of erosion in just three months.
To the shock of stunned bystanders sat on a wall just metres away the chunks of cliff top broke away from the cliff face at Birling Gap, on the East Sussex Coast and plunged onto the beach below today.
A huge crack could be seen along the top of the cliff in the moments before the stones fell, while other crevices have also formed along the edge of the picturesque coastline.
Over the weekend a 100-square-foot area of the collapsed, leaving a cottage dangerously close to the sheer 30ft drop below. … …

Teams are working to clear a “significant” landslide that blocked the promenade between Bournemouth and Boscombe’s piers.
The 20-metre wide (65ft) strip of cliff face fell onto the promenade and beach access road at around midnight.
Portland coastguard watch commander Malcolm Wright said: “
Because of the rainfall that we’ve had, the ground near cliff tops will be saturated.
“With the extra weight of water landslides are inevitable.”
… Bournemouth seafront manager Chris Saunders is already overseeing the clear-up of 387 beach huts on the borough’s coastline, which were damaged or destroyed either by landslips and storms.
He said: “It’s not an uncommon occurrence. It’s not a huge slip – we’ve had worse over the years.
“We had a cliff slip down at Gordon’s Corner, at Southbourne, just before Christmas that wasn’t quite as big as this but did more damage because it was where some beach huts were.
“About three or four years ago just the other side of the East Cliff lift we had a substantial cliff slip that went through the back of a building.
“Knowing we’ve had the heavy rains, we commissioned a geotechnical expert to come and check the cliffs through but this has slightly beaten us to it.”
A second rock fall has taken place at about midday at Monmouth Beach, Lyme Regis.
- The ancient forest was covered in peat before
eventuallybeing swallowed by the sea
- Legends say trees and nearby township were flooded after a priestess neglected a magical well
- Conditions inside the peat, devoid of oxygen and slightly alkaline, have meant the stumps survived
- They were uncovered by the latest set of storms which washed away the peat layer
Rising from the beach in a surreal seascape, the remains of these ancient trees have been revealed by the storms.
Thought to date back to the Bronze Age, the shin-high stumps became visible for the first time when the peat which once covered them was washed away in torrential rain and waves pounding the shore.
Now they stud the beach near the village of Borth, Ceredigion, Mid Wales – an area already rich in archaeology, opposite the alleged site of Wales’s own take on the lost city of Atlantis.
Folklore has it that Cantre’r Gwaelod, or the Sunken Hundred, a once-fertile land and township, was lost beneath the waves in a mythical age.
The land is said to have extended 20 miles west of the present Cardigan Bay, but disaster struck and Cantre’r Gwaelod was lost to floods when Mererid, the priestess of a fairy well, apparently neglected her duties and allowed the well to overflow.
Archaeologists knew the 5,000-year-old forest existed on the beach at Borth and stumps were sometimes visible along parts of it at low tide.
But the recent storms revealed a whole new section thought to include oak and pine near Ynyslas, further north than the previously seen remains. The stumps are preserved because of conditions in the peat.
Part of a wattle walkway, believed to date from ancient times, has also appeared. It is thought it was made from branches, sticks or logs and used for people to cross wet ground without sinking into it.
The discoveries were made by Deanna Groom and Ross Cook from the Royal Commission on the Ancient and Historical Monuments of Wales.
… The whole area was once under forest which, over time, became peaty and was then submerged under the sea as
the coastline changed over thousands of years…

caused a massive landslide on a cliff road overlooking one of the country’s best-known beaches.
But the local council said it was not concerned that the slip road leading to Ladies’ Beach in Ballybunion was in any danger of collapsing.
The latest slippage occurred on Sunday when part of the clay cliff face gave way and landed on the road. The damage has already been assessed by Kerry County Council – which did not see any reason to close off the road. A spokesman said the council would allow the earth to settle first before a further and more in-depth assessment is made.
Snuggling in the lap of the massive Brahmaputra, the gorgeous hotspot of Assam is now facing grave threats of abrasion caused by the gigantic river itself.
The largest river island Majuli is submerging due to excessive sediment discharge caused by frequent low magnitude seismic disturbances.
It has been reported that the surface area of the island, originally 1100 square kilometres has shrunk drastically and now areas 352 square kilometres.
Majuli, which means, land between two parallel rivers is located in Assam in India and is a region of fluvial geomorphology. Springing from the Brahmaputra basin and turning into a flat-leveled alluvial plain, this isle is bounded by the river Subanisri and her tributaries on the north-west and the Kherkatia Suli, a spill channel of the Brahmaputra in the north-east with the main stream on the south and south-west. These tributaries carry floods laden with fine silt and clay residue and have sheer gradient, shallow braided shifting channels and had course of sandy beds. The formation of islets, around the island locally known as Chaporis, is another significant feature, leading to braiding of the river.
With agriculture being the dominant industry and paddy being the chief crop of the island, Majuli has a profuse and heterogeneous agrarian tradition, with varieties of rice grown, without any use of pesticides or inorganic manure. However, due to heavy rainfall that Assam is subjected to, the area often experiences uncontrolled floods which in turn leads to excessive land erosion.
“Majuli was an integral part of the Jorhat district. Due to floods and changed courses of the Brahmaputra, it has been detached from the mainland. Now the present situation is becoming grave due to land erosion particularly in the last two-three decades where huge parts of the island has been eroded by the river“, says Dr Kamala Kanta Nath, a retired professor, Department of Agrometeorology, Agricultural University, Jorhat, Assam.
… Housing too has transformed from traditional bamboo and mud construction to ones made of concrete. … The only means of conveyance to the outside world is through a ferry service that is operational only twice a day.
… The island filled with a rich cultural heritage is now shrinking at a rapid rate and is a major source of concern for the inhabitants.
When it rains all our houses are washed away.
We live in boats turned into tents; families survive for months.
We live on mercy of those who send us food and clothes. We have no place to go. We have no money and no job.
We seldom know whether we will be alive the next day, says Surmaiya Chumoa, a resident of the island.
To safeguard the sinking isle, the Union Government of India has sanctioned 250 crores while the water resource department and the Brahmaputra board are struggling to solve the erosion problem of the isle for the last 3 decades to no results.
“Our Government is not so well equipped with resources to save Majuli merely with the help of loans. They will require some form of International help and huge amount of funds to save the island. The Indian and Assam Government has already spent a huge sum in making the embankments only to yield negative results. I think that if we go step by step with a long term plan to make arrangements to decrease the rate of erosion and control the floods, then perhaps we will be able to save the island”, says the retired professor.
The project, namely The Brahmaputra River Restoration Project is yet to be approved by the Government. However, a nomination has been sent to the UNESCO for the declaration of Majuli to be as a world heritage site.
