Explanation: Khajjiar Lake, located in the Chamba district of Himachal Pradesh, is a unique and picturesque lake known for its floating island. This natural wonder is a significant feature that distinguishes Khajjiar Lake from other lakes in the region. The floating island is formed by the accumulation of organic matter and vegetation that floats on the surface of the lake. This phenomenon is a result of the lake's unique ecological conditions, where the decomposition of organic material and the growth of vegetation create a buoyant mass that remains afloat.
Khajjiar Lake is often referred to as the "Mini Switzerland of India" due to its scenic beauty and the surrounding greenery. The lake is surrounded by a dense forest of pine and deodar trees, which adds to its charm and makes it a popular tourist destination. The floating island is a natural curiosity that attracts visitors and researchers alike, as it is a rare and fascinating natural phenomenon.
In contrast, the other lakes mentioned in the options do not possess this unique feature. Chandra Taal, located in the Spiti Valley, is a high-altitude lake known for its scenic beauty and proximity to the Pin Valley National Park. Bhrigu Lake, situated in the Kullu district, is a high-altitude lake with religious significance and is believed to be the abode of the sage Bhrigu. Kareri Lake, also in the Kullu district, is a popular trekking destination known for its stunning views and proximity to the Rohtang Pass.
Understanding the geographical features and unique characteristics of these lakes is essential for comprehending the natural diversity of Himachal Pradesh. Each lake has its own distinct features and significance, making them important landmarks in the state's geography and tourism. The floating island in Khajjiar Lake is a prime example of the state's rich natural heritage and serves as a reminder of the diverse and fascinating natural phenomena that can be found in Himachal Pradesh.
