Geography of Uttarakhand

Overview

Uttarakhand, carved out of Uttar Pradesh on 9 November 2000, is a Himalayan state with extraordinary geographical diversity. Understanding its physical geography is essential for UTET Paper II because questions frequently test knowledge of Himalayan zones, major glaciers, river systems and the state's rich biodiversity. This topic also connects to Environmental Studies, conservation movements (Chipko) and the cultural identity of the region.

For exam purposes, you must be able to distinguish the three Himalayan zones, name the glaciers that feed sacred rivers, trace river courses and recall key facts about national parks and wildlife sanctuaries. Map-based and factual MCQs are common, so memorise locations, elevations and protected areas.

Key Concepts

• Three Himalayan Zones: Uttarakhand is divided into the Greater Himalayas (Himadri), Lesser Himalayas (Himachal) and Outer Himalayas (Shivaliks), each with distinct elevation, climate and land use.
• Glaciers as River Sources: Gangotri and Yamunotri glaciers are the origin points of the Ganga and Yamuna rivers respectively; glaciers act as frozen reservoirs feeding perennial rivers.
• Drainage Pattern: The state has two major river systems — the Ganga system (Bhagirathi, Alaknanda and tributaries) and the Yamuna system; rivers flow south or south-west towards the plains.
• Biodiversity Hotspot: Uttarakhand lies within the Western Himalaya biodiversity hotspot; altitude variation creates multiple ecological zones from tropical to alpine.
• Protected Areas Network: The state has six national parks and seven wildlife sanctuaries, including UNESCO sites like Nanda Devi and Valley of Flowers.
• Fragile Ecosystem: Himalayan geography makes the region prone to landslides, flash floods and glacial lake outburst floods (GLOFs); sustainable development is a major concern.
• Char Dham Significance: The pilgrimage circuit (Yamunotri, Gangotri, Kedarnath, Badrinath) is closely tied to glacial and riverine geography.

Key Facts

Worked Examples

Example 1 — Identifying River Origin

Question: The Bhagirathi river originates from which glacier?

Solution:

1. Recall that Bhagirathi is the main source stream of the Ganga.
2. The Ganga's glacial origin is at Gaumukh, the snout of Gangotri Glacier.
3. Answer: Gangotri Glacier.

Example 2 — Locating Himalayan Zones

Question: Dehradun is situated in which Himalayan zone?

Solution:

1. Dehradun lies in the Doon Valley between the Shivalik hills and the Lesser Himalayas.
2. Elevation of Dehradun is approximately 640 m.
3. This falls within the Outer Himalayas (Shivaliks) range.
4. Answer: Shivalik (Outer Himalayas).

Example 3 — Protected Area Recognition

Question: Which national park in Uttarakhand was India's first and is famous for the Bengal tiger?

Solution:

1. India's first national park was established in 1936.
2. Originally named Hailey National Park, later renamed Ramganga and finally Jim Corbett National Park.
3. Located in Nainital and Pauri Garhwal districts.
4. Answer: Jim Corbett National Park.

Common Mistakes

• Confusing Bhagirathi and Alaknanda origins → Bhagirathi comes from Gangotri Glacier (Gaumukh); Alaknanda comes from Satopanth Glacier near Badrinath. Both merge at Devprayag to form Ganga.
• Mixing up Shivaliks and Lesser Himalayas → Shivaliks are the outermost, lowest range (foothills); Lesser Himalayas are the middle range with hill stations. Remember: Shivalik = "youngest and lowest."
• Forgetting the Five Prayags sequence → Use mnemonic: Very Nice Kids Run Daily (Vishnu → Nanda → Karna → Rudra → Dev Prayag, upstream to downstream on Alaknanda).
• Stating Nanda Devi is India's highest peak → Nanda Devi is the highest peak entirely within India (7,816 m), but Kangchenjunga (8,586 m) is higher; however, Kangchenjunga straddles India-Nepal border. Exam often tests this nuance.
• Confusing Valley of Flowers location → Valley of Flowers is in Chamoli district, not near Nainital. It is adjacent to Nanda Devi National Park and both are UNESCO sites together.

Quick Reference

1. Three zones (low to high): Shivaliks → Lesser Himalayas → Greater Himalayas.
2. Gangotri Glacier → Bhagirathi; Yamunotri Glacier → Yamuna.
3. Devprayag: Bhagirathi + Alaknanda = Ganga.
4. Jim Corbett: India's first national park (1936), Nainital district.
5. UNESCO sites: Nanda Devi + Valley of Flowers (combined).
6. State symbols: Musk Deer (animal), Monal (bird), Brahma Kamal (flower), Buransh (tree).
