Flanked by the mid-high 602 metres (1,975 ft) foothills Hörnle and Hohenbol to the north and northwest, both of which encompass chimneys of the Swabian volcano, it serves as a notable landmark.

The mountain's slope is characterized by the Yellow Rock, a bright limestone sponge reef from the Jura Sea.

Eastward of the Gelber Fels, three grave mounds from the Hallstatt period (800-400 BC) signify early human settlement of Teckberg.

The entire Teckberg, spanning 386.0 hectares (954 acres), was designated as a nature reserve by the Regierungspräsidium Stuttgart on November 9, 1999.

The intention behind this designation was to safeguard and foster a diversely rich cultural landscape that includes wet and dry meadows, orchards, hedges, forest edges, alleys, groves, solitary trees, rocks, caves, springs, and rare natural forest communities.
