Then, i remembered, i had been wanting to go to the salt lake that is near Middlemarch. What is it? Lake Sutton is the only saline lake in New Zealand, located in the arid region of central otago. It is recharged by rainfall only and when full is only about a meter deep. The salinity is from marine aerosols carried in rainwater from the coast about 50 km away. The aerosols are forced into the air by wave action and carried in and deposited in the lake. The lake does not always have water in it b/c it evaporates regularly due to the frequent exposure to wind. The filling and evaporation over time has created a build up of marine aerosols in the lake bed, which causes the salinity when filled. The saline environment means that a unique ecosystem has been created in the middle of an arid desert region.
So, we took off to the track, no idea what to expect we just knew it was a 4km loop that should take about an hour to walk (much longer if you go with a 4 year old who doesn't like to walk, but rather climb up on every rock). The drive from Dunedin to Middlemarch takes about an hour and you get to drive through this amazing weathered schist landscape with orange/yellow tussock. The parking lot was through an alfalfa field that were up to our car windows. And low and behold, the track to the lake was through the amazing rock landscape! The track was very easy and flat and perfect for active children who like to climb on rocks!
We got to the lake and it didn't have any water in it, but it was still cool. We had an amazing picnic upwind of the lake (b/c it smelt like death down wind) and Bodie really enjoyed jumping/climbing on the back of the sleeping dragons (i mean rocks) and hiding from the Orcs (Lord of the Rings stuff).
Great place to go with kids b/c it is an easy walk and the scenery is so amazing!
