This is only one of many narrow passages you will encounter in the Chiricahua National Park. They really make you fell tiny and the distant entrances often frame the landscape in lovely ways.
This HDRI gives you a very narrow strip of skylight, plus a large orange bounce from the sunlit rock wall. It is a bit restrictive in terms of framing, and only works for smaller objects. The two entrances have very different lighting, so some tweaks to HDR intensity are needed depending on what direction you choose...
