Namak Lake, Salt lake in Qom Province, Iran
Namak Lake is a salt lake in central Iran that stretches across the provinces of Qom, Semnan, and Isfahan. Its surface is covered by a thick crust of salt mixed with mineral deposits that appear in shades of white, pink, brown, red, and purple depending on the season and water level.
The lake is what remains of an ancient sea that covered much of the Iranian plateau millions of years ago before gradually drying out. The Qom River still flows into it today, but the water that enters is mostly lost through evaporation rather than drainage.
Along the shoreline, salt workers harvest the surface deposits by hand using tools passed down through generations, a practice still visible today in the warmer months. The work follows the rhythm of the seasons, with activity picking up as water levels drop and the salt crust thickens.
The lake is very shallow and the ground can shift between firm salt crust and soft mud depending on the season, so sturdy footwear is useful. The area has no shade, so sun protection and water are important to bring, especially since temperatures can change sharply between morning and afternoon.
The sharp swings in temperature between day and night in this desert environment cause rocks near the lake to crack and break apart over time, producing the sandy formations visible along the shore. This slow process means the edges of the lake look slightly different from one visit to the next.
