Tearing down GlobeVille

       Globeville Landing park is up on a hill and slopes down into the South Platte River. The River comes from the west and flows north east at the GlobeVille Park. As you can see from the picture below, there are buildings on either side of the river and it is rather low compared to the rest of the land. This is evidence of a low water table that is fed from the river. The buildings are build on relatively safe land when it comes to soil.

Those buildings are steel warehouses, with oil, steel, and dogfood nearby.  You can also see in this picture the way that the river has shaped the land over years and depending on its fullness the landscape looks different.
       To the west are The Rocky Mountains. On my drive snowboarding last week I noticed lots of evidence for mass wasting and weathering. From connecting fallen rocks to their source, to streams, to avalanches, it was an interesting drive.

Above: A very small avalanche slide on I-70. This steep grade caused by the cutting of the road made an un stable slope
for the snow to sit on and one day it slid out. Gravity can cause events like this, mudslides, rockfalls, and floods. 
        Globeville has a dry climate but with the river next door there is evidence on the sidewalk of salt weathering where it has changed colors. Oxidization on the bridges shows itself in rust and some of the round rocks near buy have a hard weather rind. 

Above: Rocks like this can be found near GlobeVille Landing Park. Notice the small holes  on the rock caused by salt weathering. Also the discoloration is evidence of the rock's weather rind also known as the weather ring.
