    This study highlights a geology of Yosemite Valley virtual field trip (VFT) and the companion exercises produced as a four-part educational activity to substitute physical field experiences. The VFT is created as an Earth project in Google Earth Web, a versatile format that allows access through a web browser or Google Earth application with the sharing of an internet address. Many dynamic resources can be used for VFT stops through use of the Google Earth Engine (global satellite imagery draped on topography, 360∘ street-level imagery, and user-submitted 360∘ photospheres). Images, figures, videos, and narration can be embedded into VFT stops. Hyperlinks allow for a wide range of external resources to be incorporated; optional background resources help reduce the knowledge gap between the general public and advanced undergraduate students, ensuring that VFTs can be broadly accessible. Like many in-person field trips, there is a script with learning goals for each stop, but also an opportunity to learn through exploration, as the viewer can dynamically change their vantage at each stop (i.e., guided-discovery learning). This interactive VFT format supports students' spatial skills and encourages attention to be focused on a stop's critical spatial information. The progression from VFT and mapping exercises to geologically reasoned decision-making results in high-quality student work; students find it engaging, enjoyable, and educational.
