Western Arthurs Day 7 : Haven Lake - Mt. Scorpio - Promontory Lake

Western Arthur Range Index

Lakes Galore


It was dawn of the seventh day and breaking camp had become an established routine - a change clothes, coffee, a visit the privy, and some breakfast, before replenishing my water supply and packing my bag. Once I was ready to set off, I made my way along the trail and continued up the hill for approximately 100 metres Eastwards towards the viewpoint that was located on the saddle. I turned left here to continue along the main track instead of turning right, which would have taken me on the 2-3 hours return trip to the summit of Mt. Aldebaran (elevation : 1107m) and continued on past the magnificent views.

The peak on the left was skirted as we pushed through more vegetation, with the trail gradually making its way upwards and opening itself up to more spectacular views before descending down once again to another saddle. By now the sun was out and my body was soaking in the warmth of its rays. Seemed as though a few lizards had the same idea as they furtively skulked out from cracks in the rocks to bask in the sun. Thermoregulation like this helps to stimulate their metabolism and keeps their muscles limber for hunting or to escape predators. I eventually found myself climbing up to round a ridge just before Lake Sirona presented herself. The track could be easily seen disappearing off into the distance.

The path continued along the ridge all the way to the edge with Lake Sirona just below, before descending vertically down the gully to the shores of the lake itself. We took care here with the down-climb, ensuring that our heavy backpacks wouldn't tip us over backwards. The trail continued North-East across and over to the broad moor with Lake Sirona on the left and Lake Mars far off on the right, leading gradually up towards the a boulder-filled area with the peak of Mt. Scorpio (elevation : 1106m) just beyond. Grasshoppers hopped across me and other insects buzzed around me as I made my way through the grass of the moor. As I made my way forwards, the grass lessened and the path began to rapidly thin as rocks began to take over once again, with quite a few of them topped with basking diurnal skinks (Family : Scincidae).

After sidling the summit of Mt. Scorpio, the path swung left to head Northwards before continuing North-East down a gully. Here, the views of the open plains appeared ahead of me with the clearly visible track down Kappa moraine snaking its way down to the Arthur Plains below. Seeing the track leave the range brought in a twinge of sadness as I realised that the hike would eventually be coming to an end. If you choose to continue left down Kappa moraine from the junction, following the trail for about 5km (approximately 2 hours of walking) will bring you to Seven Mile Creek.

To the right, across to the East, the views of Lake Promontory off in the distance and Lake Juno nestled under the cliffs kept me entranced (Lake Vesta remained hidden). I was quite aware of the absolute size of each lake but the similarity of their apparent size created the strong illusion of them being a similar distance away, when in actual fact Promontory lake was so much bigger, higher and much further away. The stark contrast of the different shades of each lake was also extremely fascinating - the light blue water of Lake Promontory reflecting the sky and the dark, almost black water of Lake Juno darkened by the shadows of Carina Peak's (elevation : 1008m) North-Western cliffs that lay just above.

Onwards to Lake Promontory


Turning right at the Kappa moraine junction brought us down a steep descent to Lake Juno through fairly thick vegetation, the path narrowing and the sides closing in. Carcasses of long dead trees stuck out occasionally obstructing the trail and the trickling of a stream that ran down the path kept our boots wet. Everything here seemed a little surreal. As the track began to climb once again past the two lakes and up to Lake Promontory with the Northern cliffs of Carina Peak towering above us, the vegetation began to close in. It was fairly overgrown here and we were forced to push our way through, scratching and scrambling our way upwards.

As the scrubby bush began to let up and the surroundings opened up to reveal tall formidable shells of once-living trees that lined the lake, we made our way forward to circle the Northern shores and around to the South-Eastern corner of the lake. The terrain here was quite muddy, especially around the fast-flowing river, but once over the river the terrain improved a little and we drew nearer to the clearings that are used for camping, sheltered by the hills just beyond. Located right next to the lake, the Promontory Lake Campsite was the most scenic campsite so far; but since it had no 'facilities', was also the most bare - one has to go above and over the hill to relieve oneself so as to not contaminate the water catchment area.

Day 8 : Inclement Weather


We had inclement weather that night, with heavy rain starting around 4 in the morning and continuing on throughout the next day. The mist rolled in when the rain subsided, blanketing everything in a complete whiteout, leaving us stranded in the campsite, completely unable to move. This forced us to seriously re-evaluate our options, and because we were aware that the next stage of the hike to Lake Rosanne would be through thick scrub, mostly on an exposed ridge, and could occasionally be hard to follow, we glumly began to prepare ourselves of the possibility of exiting the range through Kappa moraine once the weather cleared.
