The 7 coloured soil formation is the result of a natural geological process
The seven-coloured soil formation at Raireshwar, a rare natural heritage in Pune's Bhor district, is facing an increasing threat from visitors. Locally known as Vibhuti Chi Khan or Vibhuticha Dongar, the geological wonder is being disturbed by tourists, amateur researchers, and history enthusiasts who reportedly dig into the formation and carry away samples out of curiosity.
The issue has assumed significance on International Geodiversity Day, observed on October 6, with environmentalists and local residents calling for immediate and permanent protection of the geological formation.

According to the locals, the increasing popularity of the site has brought more visitors to the location. "If it is not protected today, there could come a day when the authorities will have to put up a board saying that this site was the place where seven colours of soil were once found. Because of social media and reels, tourists and enthusiasts have been coming here, digging up the formation, and taking away the soil out of curiosity," said Sandeep Jangam, a Raireshwar resident.
"There should be a ban on taking the soil or even touching the formation. We want a permanent solution to protect this historical and natural wealth for future generations," he said.
Environmental groups and local organisations are seeking recognition of the seven-coloured soil formation as a Geological Heritage Site. Dr Punekar said such recognition could provide a framework for long-term conservation. "Based on our studies and interactions with local residents, we believe that granting this unique habitat Geo-Heritage status would help ensure its permanent protection and conservation. We have been pursuing the matter with the concerned authorities," he said.
Raireshwar holds a special place in Maharashtra's history, as this is where Chhatrapati Shivaji Maharaj took the oath of Hindavi Swarajya along with his Mavla companions in 1645.
Shital Rathod, assistant conservator of forests (territorial), told mid-day that the department became aware of the issue after she was transferred to the area last year. "When I was transferred here last year, we came to know about the issue. We immediately initiated the process of putting up barricades around the site. However, the barricading was on the outer side. We are now planning to put up additional barricades on the inner side as well," Rathod said.
A geological wonder
The plateau is also known for its rich natural heritage. During the monsoon, it is covered with colourful wildflowers, giving it the appearance of a natural flower plateau. Its geological formations add another important dimension to its heritage value.
According to Dr Punekar, the seven-coloured soil formation is the result of a natural geological process that has taken place over a very long period.
The rainfall in the Sahyadris has caused the weathering and erosion of basaltic rocks over millions of years, leading to the formation of laterite - a soil rich in iron, also containing aluminium-bearing minerals such as bauxite. Iron oxides and other mineral components contribute to the striking colours seen in the soil.
Dr Punekar
The natural formation should not be viewed simply as coloured soil that can be collected as a souvenir. "This is a unique geological heritage formation created through natural processes over a very long period. Removing the soil or disturbing the formation can permanently damage its natural character. What is required is regulated, controlled, and sustainable tourism," he said.
