1. Hallasan

Hallasan (한라산, 漢拏山) is the highest mountain in South Korea and is one of its most iconic natural landmarks. Located on Jeju Island, a volcanic island designated a UNESCO World Heritage Site, Hallasan dominates the landscape, playing a crucial role in the island's climate, hydrology, and biodiversity. This article provides a comprehensive overview of Hallasan, covering its geological formation, ecological significance, hiking trails, cultural importance, and current conservation efforts. It aims to serve as a definitive guide for both prospective visitors and those interested in understanding the natural history of this remarkable mountain.

Geological Formation

Hallasan is a complex volcano formed through multiple stages of volcanic activity over hundreds of thousands of years. Its formation began during the early Pleistocene epoch, approximately 25,000 to 500,000 years ago. The initial stages involved submarine eruptions, building up a shield volcano foundation. Subsequent eruptions, particularly during the late Pleistocene and Holocene epochs, added layers of lava flows, ash, and pyroclastic materials, gradually constructing the present-day cone shape.

The volcano isn’t a typical, single-event creation. It's a composite volcano exhibiting characteristics of both shield and stratovolcanoes. The lower slopes are gentler, formed by fluid basaltic lava flows, while the upper slopes are steeper, reflecting the more viscous and explosive eruptions of later stages.

A significant geological feature is the large caldera at the summit, known as Baengnokdam (백록담, 白鹿潭, “White Deer Lake”). This caldera was formed by a massive explosive eruption approximately 25,000 years ago, which collapsed the summit. Baengnokdam now holds a crater lake, fed by rainwater and snowmelt. The lake’s water level fluctuates significantly depending on precipitation.

The volcanic rock composing Hallasan is predominantly basalt, but also includes trachyte, andesite, and rhyolite, indicating a changing magma composition over time. The presence of various rock types provides insights into the dynamic geological processes that shaped the mountain. The surrounding landscape also features numerous parasitic cones, lava tubes (such as the Manjanggul Lava Tube, another UNESCO World Heritage Site), and ore deposits, all stemming from Hallasan’s volcanic activity. Understanding the geological history of Hallasan is crucial for assessing potential volcanic hazards and implementing appropriate monitoring strategies. Geological surveys continually monitor seismic activity and gas emissions to detect any signs of renewed volcanic unrest. Volcanic Discovery - Hallasan provides updates on volcanic activity.

Ecological Significance

Hallasan’s elevation and geographical isolation have resulted in a unique and diverse ecosystem. The mountain exhibits altitudinal zonation, with distinct vegetation bands corresponding to changes in temperature, precipitation, and soil conditions.

• **Subtropical Forest (below 500m):** The lower slopes are characterized by a warm, humid subtropical forest dominated by evergreen broadleaf trees such as Camellia japonica, Machilus thunbergii, and evergreen oaks. This zone is similar to vegetation found in southern Japan and Taiwan.
• **Temperate Forest (500-1100m):** As elevation increases, the subtropical forest transitions into a temperate forest with deciduous trees like Quercus acutissima and Castanea crenata. This zone also includes a mix of evergreen trees and shrubs.
• **Subalpine Forest (1100-1500m):** Above 1100m, the forest becomes dominated by Pinus densiflora (Korean red pine) and Abies koreana (Korean fir). This zone experiences colder temperatures and heavier snowfall.
• **Alpine Meadow (1500m and above):** Above the treeline, the landscape transforms into an alpine meadow with low-growing grasses, wildflowers, and dwarf shrubs. This zone is characterized by harsh conditions and a short growing season.
• **Baengnokdam Zone:** The area surrounding the crater lake supports specialized alpine vegetation adapted to the extreme cold and windy conditions.

Hallasan is home to a remarkable number of endemic species – plants and animals found nowhere else on Earth. Approximately 57% of the plant species on Jeju Island are endemic, many of which are concentrated on Hallasan’s slopes. Notable endemic plants include *Coreopsis hallasanensis* (Hallasan coreopsis) and *Rhinanthus pseudomontanus* (Jeju Rhinanthus).

The mountain also supports a diverse fauna, including the Jeju dark field mouse (*Apodemus chejuensis*), a rodent endemic to Jeju Island, and various bird species, including the Jeju subspecies of the Japanese bush warbler. Deer, wild boar, and other mammals also inhabit the lower slopes. Jeju Island Official Tourism - Hallasan Ecosystem details the biodiversity.
