This week I journeyed to the beautiful hiking trails in the Lamington National Park in South East Queensland, Australia. Right next to O'Reilly's Rainforest Retreat, this trail walking video is perfect for all ages. I hope you enjoy this gentle rainforest walk and also learn something new about the area from the signs along the way. I have written out the signs below if you can't read them in the video. Happy hiking!

The 'time walk' :
✨ 1 ✨
Welcome to the time walk...
Walk 23 million years of Lamington's history along this 700m track and discover what happened to this landscape through time. You are starting your walk 23 million years ago-it is the beginning of the Miocene era and the Australian continent has separated from Antarctica and is moving north. The seas are rising making Tasmania an island; the climate is warm and wet, and species such as carnivorous marsupials roam the landscape. Discover more of the park's history with every step. Every 100m equals about 5.5 million years.

You are walking on the remaining north-western flank of an ancient volcano, one of several that erupted down eastern Australia from 34 to 6 million years ago. Some 23 million years ago the last basalt lavas from the 2000 metre-high Tweed Volcano flowed down this slope.
Here a thicker, more resistant basalt lava flow did not erode as fast as the surrounding flows; the result was a ridge with boulder outcrops such as this rock. To touch this rock is to touch the last lavas that flowed from the volcano-essentially a 23 million year old rock.

You may not feel it but this mountain is moving! Evidence is the valley before you-it is still deepening and widening. It began when the high peak of the extinct volcano attracted heavy rains. Slowly and steadily the trickle of water formed rivulets, streams, and then eventually rivers all radiating from the volcano's peak. Slowly valleys were eroded, some deepening to expose cliff-lined gorges between broad plateaus and eroded narrow ridges. Soil creep, landslides and creek erosion continues today.

Some of Lamington's plants are survivors of prehistoric times; some ancient fern families date back 300-400 million years. The hoop pine, belonging to the plant genus Araucaria, is one of the most ancient and primitive of the world's conifers. When Australia was still part of Gondwana, some 200 million years ago, these conifers were widespread having replaced ferns as the main terrestrial plant type. Today hoop pines.only grow in a few isolated Jocations and mostly within the Gondwana Rainforests of Australia World Heritage Area. The largest undisturbed stand of hoop pine remaining in Australia is located in Lamington National Park.

Imagine coming face to face with the largest marsupial ever to live in Australia- the diprotodon. Weighing about 3 tonnes and standing 2m tall at the shoulder, this large, wombat-like marsupial, was widespread across Australia from about 5.3 million years ago. It could have wandered the lower slopes of this eroding volcano browsing on shrubs and herbs. and using its chisel-like incisors to dig out vegetation. As a marsupial, the diprotodon would have carried a single enormous joey and moved in moderate-sized herds as kangaroos do today. The diprotodon co-existed with Aboriginal people for thousands of years before becoming extinct.

About 20,000 years ago Australia weathered an ice age that lasted for some 5,000 years! Lamington then would have experienced falling temperatures, decreased rainfall, and cold dry winds blowing through the canopy. Parts of Australia became a stark and inhospitable landscape, lakes dried up, forests disappeared, deserts expanded and many animals became extinct. Sea levels also fell some 100m allowing connections between mainland Australia, Tasmania and New Guinea. The ice age threatened the very survival of Aboriginal people who had arrived some 30,000 years earlier. It has been suggested that up to 60% of the entire population may have perished during this ice age.

You have walked 23 million years of Lamington's history. The last few metres you entered the Holocene epoch-10,000 years ago to the present. You are now here, but you have so much further to walk if you are planning to discover more of this park. Tread carefully and tread softly and help protect this world heritage rainforest so others may experience its wonders too; take only photos and leave only footprints.
