A six layer model of southwestern Ontario's Paleozoic bedrocks by geological age. Higher detail and more layers than the original four layer model (printed using a fine 0.2 mm nozzle). Each layer is removable (Cambrian is combined with Middle Ordovician due to thickness). The featured layers are Devonian (green), Silurian Salina (purple), Silurian Guelph-Cataract (yellow), Upper Ordovician (blue), Middle Ordovician + Cambrian (light blue + orange), and Precambrian (red). The cities of London and Toronto are marked and key labels are in bold black text. This model is printed at 1 to 2.5 million scale and measures approximately 24 cm x 16 cm x 10.5 cm (LxWxH). Great for any geologist and a worth upgrade from the four layer model!
