+The purpose of this lesson is to review the change from leaf-off imagery to leaf-on imagery for a study areas of interest.  
+
+In this lesson, you will:
+
+* Choose an area and Landsat collection of interest;
+* Filter the Landsat collection to obtain leaf-off and leaf-on imagery; and,
+* Display a single image from both leaf-off and leaf-on conditions.
+
+## Data Acquisition & Pre-Processing
+```{code-block} javascript
+// Define boundary for Rocky Mountain National Park, Colorado
+var rmnp_boundary = ee.FeatureCollection("users/calekochenour/Rocky_Mountain_National_Park__Boundary_Polygon");
+
+// Define Landsat 8 collection
+var landsat8_t1_sr = ee.ImageCollection('LANDSAT/LC08/C01/T1_SR');
+
+// Filter Landsat 8 Tier 1 SR to snow-on conditions near RMNP, 2018
+var co_snow_on_2018 = landsat8_t1_sr
