// Sentinel-2 surface reflectance image collection.

// Filter the images to those that intersect Mount Shasta for 3 months
// in 2019 and 2021 (two image collections).
var geom = ee.Geometry.Point(-122.196, 41.411);
var ic2018 = ic.filterBounds(geom).filterDate('2019-07-01', '2019-10-01');

print('2021 image collection', ic2021);

// Merge the two image collections.
var icMerged = ic2018.merge(ic2021);
