River Rafting and Sandbar Soccer

Sunny and warm weather on the first weekend of fall was perfect for a couple of activities for Earth and Environmental Science students along the shores of the Minas Basin. On Saturday, a small group headed out to Rainy Cove to join students from the Dalhousie petroleum geoscience course, led by Grant Wach (Dal) and Carla Skinner (Shell, Calgary). At low tide they ventured out to the giant sand bar to examine the megaripples developed there.

Kirklyn excavating a trench in a megaripple to examine the sediment build-up, calculated to have formed over the course of three months, based on coarser grained layers deposited during spring tides.

Returning from the sandbar, the group crossed a broad channel, scoured free of sand by the tidal currents. What better place is there for an Acadia-Dalhousie soccer game?

Alex on the ball, about to pass to Kirklyn, who forwarded it to Sarah to score the first goal. Acadia up 1-0 after 2 minutes. We won't say anything more about the next 4 goals scored by Dalhousie, except that they did have some of the Dal soccer team playing for them. Game was cut short at 25 minutes by incoming tide.

Back at the cliffs, Grant Wach expounded on the similarities between tidal sand bars in the modern environment and Triassic fluvial sandstone and conglomerate deposits:

Finally the group encountered the famous Triassic angular unconformity at Rainy Cove:

On Sunday, another group ventured along to Maitland to experience the tides up close, rafting on the tidal bore. clearly they also encountered sandbars, waiting for the tide to come in:

Much fun was to be had getting dirty in the mud along the river banks:

Finally, the tidal bore arrived and everyone got cleaned off:
