Hongtu Nur is located in the central part of Zhenglan Banner, Xilin Gol League, Inner Mongolia Autonomous Region, in the heart of the Hunshandake Desert, close to the Beijing-Tianjin area. "Hongtu" means swan in Mongolian, and "Nur" means lake.
As a rare inland seasonal salt marsh lake, it is special in the following ways:
Sand and spring symbiosis: The lake water originates from underground fault springs (annual average flow of 50,000 m³) and is surrounded by crescent-shaped sand dunes, forming a dynamic balance of "sand in and spring out".
Two-color lakeshore: the white sand on the east bank is as pure as snow (quartz sand content is 92%), while the red willows on the west bank are lush and flaming, and aerial photography shows a Tai Chi diagram.
Grasslands: Surrounded by vast meadow grasslands, rich in vegetation, supporting a diverse fauna.
Ecological characteristics: It is the habitat of many rare wild birds, such as swans, geese, etc.
Swan Station: During the spring and autumn migration seasons (April-May/September-October), over a thousand whooper swans visit the station, creating a "bird wave" that resembles a white storm at dawn and dusk.
Sandy medicine storehouse: Sandy medicinal herbs such as Cistanche deserticola and Cynomorium songaricum grow around the lake. Herders must follow the ancient rule of "taking the big and leaving the small" when collecting them.
During the peak spring season (May-June)
, groundwater is abundant, the lake area reaches its peak (about 3.8 km²), and the sand dunes are reflected like a mirror.
Swan season (early April/late September):
Swans molt en masse, and young birds create "water fireworks" as they learn to fly.
During the polar night (December-January),
the lake is frozen like obsidian, and the Milky Way arches over the sand dunes.
Scientific methods for observing the spring
:
Use a metal rod to probe the spring (consistent water temperature 8°C), take a water sample to test the pH (provided test paper indicates a weak alkaline pH), and
make a rubbing of the "ripple stone" (a relic of the ancient lakebed) on the lakeshore to compare the current and past water levels.
Photography tips: Drones are limited to a height of 150 meters. For aerial photography of the "Shaquan Tai Chi Diagram," wear indigo clothing to enhance the color contrast.
The historical secrets of the Xianbei Altar Ruins
: 1.5 kilometers from the north bank of the lake, the Xianbei people built an altar (22 meters in diameter) with stone in the 4th century AD, and threw a bronze pony during sacrifices (now in the Xilin Gol Museum)
.
Look for the "Astrological Stone" (with the Big Dipper carved on it) in the southeast corner of the altar; look for
arrowhead fragments exposed on the surface after a sandstorm (don't take them away! You can exchange them for milk tea from the herdsmen for photos).
The resilience of the red willow maze
: The roots of the 300 mu red willow forest on the west bank reach 15 meters deep. In September, the purple-red flower spikes resemble a haze, and sand foxes and jerboas scurry through
the forest .
Learn to make fire by drilling wood with red willow branches (herders teach the 45° angle friction method);
identify edible sand onion (serrated leaves) and the poisonous weed wolfsbane (purple-red flowers).
