A relatively easy three-stage cache that should be done when the tide is moderately low.
Both stages 1 and 2 are locations of dinosaur footprints made in the Bohemian Age, between 124 and 119 million years ago.
In both cases you are looking for smallish stones to which are attached metal plaques, encased in plastic covers.
At the given coordinates (Stage 1), obtain the last three digits of the northing coordinates of the final cache site and, at Stage 2 obtain the last three digits of the westing coordinates. You are looking for small metal plates encased in plastic and painted with the 3-digit coordinates. The plates are attached by wire to small rocks.
At the Stage 1 coordinates (about 500m eastwards along the beach from Salema) there are 7 footprints embedded in the rock that were made by 3 individual dinosaurs, one heading south and the other two north-east. They were bipedal (two-legged) tridactyls (three-toed) theropods (carnivores or meat eaters). They had sharp claws at the ends of long, narrow digits, v-shaped heels and held their tails in the air. The height of their hips ranged from approximately 74cm to 1.13m. One individual was walking at approximately 3.5 km/hour. The footprints are not easily seen. Look for them embedded in a rock face that rises from the beach and which is angled at about 45º.
The second set, at Stage 2, are much more easily identified than those in Stage 1 and are located at N37º 03.865’; W 008º 49.609’. This is about 200-300m westward along and above the beach from Salema. They consist of a set of footprints that were made by a single bipedal, tridactyl Iguanodontid (large ornithopod). This herbivore or plant-eater was walking westwards. The footprints have short, rounded digits with no claws and U-shaped heels. They are slightly rotated inwards indicating that the dinosaur was pigeon-toed. This meant that the dinosaur’s hips swivelled with each stride. The tracks are aligned almost one in front of the other forming a straight line. This meant that the dinosaur stood upright with its legs positioned directly underneath its body. Its hip height was approximately 2.48m and it had an approximate body length (from the top of its head to the tip of its tail) of 6 to 7 meters. It was walking at the leisurely speed of 1.66 km/hour.
The final cache is a medium sized plastic container. Team Caracache kindly reset Stages 1 and 2 on my behalf and, in the process checked on the final coordinates which differed a little in the northing only, from the ones provided by the Stage 1 plaque. If you have trouble add .004 to the northing coordinates.
