Hmm, there were several triggering events that promoted westward expansion of the United States. Victory in war over Mexico (1848) gave the US new lands in the west. A treaty with Britain (also in 1848) gave the US sole possession of some formerly disputed Oregon territory lands also. Plus, in 1848, gold was discovered in California (land newly in US possession after that Mexican war treaty), so that prodded westward expansion too. Perhaps those are the initial "turning points" you're looking for. The completion of the Transcontinental Railroad in 1869 sure helped the process as it was underway, as well.

Do you need help using primary sources to teach about the Age of Exploration? I have spent hours digging through the Library of Congress and National Archives to find the best, student-friendly primary sources.

The answer is summed up in this great quote from docsteach.org (the National Archive’s tool for teaching with primary sources).
Sources are used in a paper to show what ideas inspired you and whose theories you would be using and you cite the sources in order to avoid plagiarism. If you don't have sources, your paper will not be valid and you could get accused of plagiarism.
