Rajasthan

Sambhar Lake, India's largest inland saline lake, sits in a shallow tectonic depression in the Aravalli range roughly 80 km southwest of Jaipur, spanning parts of Jaipur, Nagaur, and Ajmer districts. Like the Caspian Sea and Dead Sea in Part 1, it has no outlet — the Aravalli hills feed it seasonal streams, and evaporation alone removes water, concentrating salt that has been commercially harvested here since at least Mughal times (Sambhar has historically supplied a very large share of India's inland salt production). It is a Ramsar-designated wetland, important for wintering flamingos and other migratory waterfowl, and is a periodic site of mass bird die-offs linked to avian botulism outbreaks during drought years — an environmental detail that occasionally surfaces in current-affairs-linked questions.

Pushkar Lake, near Ajmer, is far smaller than Sambhar but carries outsized religious and cultural significance — it is one of Hinduism's holiest lakes, ringed by ghats and the famous Brahma temple (one of very few dedicated Brahma temples in India), and hosts the annual Pushkar Camel Fair on its shores. Legend attributes its origin to a lotus petal falling from Brahma's hand, giving it a mythological (rather than a strictly tectonic/glacial) creation story worth knowing distinctly from Sambhar's geological one.

Memory hook: "Sambhar's salt is Rajasthan's largest saline superlative; Pushkar's lotus-petal legend is Rajasthan's holiest lake, not its biggest." Keep the "largest" answer and the "holiest" answer in two separate mental boxes.

Practice Recall: Before reading on, name India's largest inland saline lake and the state it is in, and name the smaller Rajasthan lake famous for its camel fair and Brahma temple.

Answer: Sambhar Lake, Rajasthan; Pushkar Lake.

Udaipur's artificial lake cluster deserves separate mention because it is Rajasthan's other major lake identity, entirely distinct from Sambhar's salt-pan geology — Udaipur is popularly called the "City of Lakes" for a chain of interconnected artificial lakes built by successive Mewar rulers, chiefly Lake Pichola (created in 1362, later enlarged, and home to the City Palace and the Lake Palace hotel built on an island within it) and Fateh Sagar Lake (built later, in the 17th century, and enlarged further in the 19th century). Both are reservoirs in origin, not natural lakes, making Udaipur a useful contrast case to remember whenever a question tests "natural vs. artificial" using a scenic rather than obviously industrial-sounding example — students often assume a picturesque palace-lake must be natural, which is exactly the assumption this pairing is designed to test.

Memory hook: "Sambhar's salt is natural and tectonic; Pichola and Fateh Sagar are man-made palace lakes built centuries apart by Mewar rulers." Rajasthan's natural-vs-artificial contrast, in one line.
