Used this app in the Wasatch. Was very easy to record data. Especially like the ability to automatically record position, slope angle, and aspect. All SWAG compatible nomenclature. Easy to enter using standard iPhone number wheels. Nice to be able to complete the pit documentation as you enter it. Once everyone starts using it and uploading their OBS as they take them, it will be a new breakthrough in social media (a true face book). Imagine checking snow pit data collected by all local tourers while you are in your assessment process in the field! Sarge
