🏞️ Explore the Avon River and Southern Highlands Escarpment

Discover the rugged sandstone ridges, deeply incised river valleys, protected drinking-water catchments and forested escarpment landscapes of southeastern New South Wales with the Avon River 9029-3S Topographic Map, sourced from the official NSW Spatial Services Topographic Map Series.

Covering the Avon River catchment between Yerrinbool, the Upper Nepean highlands and the Illawarra escarpment, this detailed 1:25,000 topographic map provides valuable geographical information for environmental researchers, catchment managers, engineers, surveyors, emergency services and geographical education.

Avon River and Lake Avon

The Avon River flows through a rugged landscape of forested sandstone valleys, steep slopes and narrow tributary catchments.

The river contributes to Lake Avon, an important reservoir within the Upper Nepean water supply scheme, which supplies water to Greater Sydney and the Illawarra.

The landscape illustrates reservoir catchment management, drainage patterns, erosion, sediment transport and water-resource conservation.

Nepean River and Upper Nepean Catchment

The Nepean River traverses the western portion of the sheet, accompanied by steep wooded valley sides, tributary creeks and protected catchment land.

The surrounding Upper Nepean State Conservation Area protects substantial areas of native vegetation and important drinking-water catchments.

Public access is restricted, making the sheet particularly valuable for authorised professional reference, environmental research and terrain analysis, rather than unrestricted recreational exploration.

Yerrinbool and the Southern Highlands

Yerrinbool occupies the northwestern portion of the mapped landscape, near the Hume Motorway and Main Southern Railway.

The surrounding highlands contain forested ridges, rural properties, transport corridors and steep creek valleys.

Historic railway tunnels and mountain transport routes illustrate the challenges of connecting the Southern Highlands and Illawarra through difficult terrain.

Mount Lindsey and Escarpment Landforms

Mount Lindsey, Mount Cotopaxi, Mount Burke and Mount Roroson provide distinctive elevated landmarks across the landscape.

The surrounding country contains rocky slopes, narrow spurs, saddles, deeply dissected gullies and forested escarpments.

These landforms provide excellent examples of sandstone erosion, geological weathering, mountain drainage and elevation change.

Illawarra Escarpment and Native Forest

The eastern portions of the sheet include landscapes associated with the Illawarra Escarpment State Conservation Area.

Native forest, sheltered gullies and steep rocky slopes contribute to the ecological character of the region.

The map is useful for studying vegetation patterns, biodiversity corridors, protected landscapes and bushfire behaviour.

Catchment Research and Field Navigation

At 1:25,000 scale (1cm = 250 metres), detailed contours and grid references help interpret river valleys, reservoir margins, escarpment ridges, fire trails and terrain gradients.

The sheet is especially useful for water catchment management, authorised field surveys, environmental monitoring, engineering investigations and emergency planning.

Professionally printed by Mapworld, available in standard paper, waterproof and tearproof DuPont™ Tyvek®, and laminated finishes.
