<P> Per the plate tectonics, Assam is in the eastern most projection of the Indian Plate, where it is thrusting underneath the Eurasian Plate creating a subduction zone . It is postulated that due to the northeasterly movement of the Indian plate, the sediment layers of an ancient geocyncline called Tethys (in between Indian and Eurasian Plates) have been pushed upward to form the Himalayas mountain range . Karbi Anglong plateau, which is situated to the south of the Kaziranga (along with the Khasi and Garo Hills) is originally part of the South Indian Plateau system . It is believed that due to the force exerted by the north - eastwardly movement of the Indian plate at the time of the Himalayan origin, a huge fault was created between the Rajmahal hills and the Karbi - Meghalaya plateau . Later, this depression was filled up by the depositional activity of numerous rivers . Today the Maghalaya and Karbi Anglong plateau remains detached from the main Peninsular block . Average height of this plateau varies from 300 metres (984 ft) to 400 metres (1,312 ft). </P> <P> Kaziranga National Park's landscape is the creation of natural forces of silt deposition and erosion that has been effected by the river Brahmaputra over hundreds of years . This ongoing process of erosion and deposition becomes more severe during the floods which occur at regular intervals during the monsoon season . The Brahmaputra river in its 724 kilometres (450 mi) flow through Assam receives more than a hundred tributaries flowing down from the adjoining hills . Once the tributaries hit the river valley, they lose their momentum; deposit the silt they carry, form ox - bow lakes and alluvial fans and branch out before picking up their courses again to join the Brahmaputra . </P> <P> Kaziranga is one of the largest tracts of protected land in the sub-Himalayan belt, and due to its high species diversity and presence of high - visibility species, has been described as a "biodiversity hotspot". </P> <P> The park is located in the Indomalaya ecozone, and the dominant biomes of the region are Brahmaputra Valley semi-evergreen forests of the Tropical and subtropical moist broadleaf forests biome and a frequently flooded variant of the Terai - Duar savanna and grasslands of the Tropical and subtropical grasslands, savannas, and shrublands biome . </P>

Which of the following does not pass through the kaziranga national park
