Keeragala

Keeragala is a geological formation found in Sri Lanka. It is characterized by large, rounded boulders, often appearing as if they have been placed there by natural forces. These formations are typically composed of gneiss, a common type of metamorphic rock. The term "Keeragala" itself is of Sinhalese origin, with "keera" meaning parrot and "gala" meaning rock, suggesting the rocks might resemble the coloration or shape associated with parrots.

These striking geological features are often found in the drier regions of Sri Lanka, particularly in the North Central and Eastern provinces. They are a result of long-term weathering and erosion processes. Over millions of years, the surrounding rock has been worn away, leaving behind the more resistant core boulders. The rounded shape is a common outcome of spheroidal weathering, where joints in the rock are attacked by chemical processes, gradually rounding the boulders.

Keeragala formations can be quite prominent in the landscape, sometimes dominating hillsides or open plains. They have historically served as landmarks and, in some instances, have been incorporated into ancient settlements or religious sites due to their imposing nature. The visual impact of these large, scattered boulders has also contributed to local folklore and legends. They are a notable feature of Sri Lanka's diverse and geologically rich terrain.
