GIS 4048: Week 2 - Lahars

This weeks topic started our coverage of natural hazards, specifically lahars.  The term lahar describes a hot or cold mixture of water and rock fragments flowing down the slopes of a volcano and/or river valleys.  Our main focus throughout this assignment was Mt. Hood, which is a massive volcano located in Oregon.  We were given the ability to learn how to use new, and different tools within ArcMap.  Such as the Fill Tool, the Flow Direction Tool, and the Flow Accumulation Tool.  All of which are used for Spatial Analyst Hydrology.  
In the map shown below, I created a 0.5 mile buffer of the stream feature.  I then used skills I've learned in the past to show affected schools and block groups within that buffer.  I also listed all of the schools that would be affected in alphabetical order.
