Congratulations to the winner of the Geobake 2025: Deam Drill Core by Alicia Mckean
Alicia described her entry:
Drill Core of Otago Schist, showing faulting, quartz veins, chlorite and gold locked in the Quartz. Made on a Swiss cream roll.
Alicia wins a one year subscription to the GSNZ for her efforts.
Thank you to everyone who took part in the Geobake across the country and sent in their entries to be judged, as always the standard was extremely high.
This year we awarded two special prizes to two young bakers (aged 8 and 12). Each has been sent a special prize to encourage their interest in geosciences. You can see their creations below.

Pink and White Terraces by Peata Gillespie (aged 8, with some help from her mum)
I 1886 i mōtī a Tarawera i Te Otukapuarangi me Te Tarata. Ko tēnei keke, he orite ki te tohu i kite i ngā tangata.
In 1886 Tarawera destroyed the Pink and White Terraces. This cake is based on the waka tohu seen by Māori before the eruption.

Geos by Anntoinette Thompson (aged 12)
Geos are made when there's hollow cavities inside a rock, these are filled in with mineral deposits around a thousand or more years, with crystals lining the inner walls of a rock. This usually happens when there are pockets of air within the rocks.
Often this is after a volcanic eruption once the lava has cooled, and there are air pockets still within the lava. This is not always the case they can be formed by groundwater seeping into a rock. But the water does not produce geodes-it brings along minerals which stay inside the rock even after the water has proceeded to evaporate.
The geo that I have created, has not taken over a thousand years to form but over a thousand minutes of molding, shaping, making edible crystals, and making it vegan to help protect the earth and our fellow creatures.
