The Dodge showing is located at the southeastern end of Windy Arm, Tagish Lake, two kilometers south of the British Columbia/Yukon Territory border. The South Klondike Highway extending from Skagway, Alaska to Whitehorse, Yukon provides access to the southwestern shore of Windy Arm. The showing area lies less than 1 kilometre from the road and can be reached on foot in summer or over the lake ice in winter.

The Dodge is located within folded Lower Jurassic Laberge Group (Inklin Formation) greywacke, siltstone and argillite at the northwest trending fault contact with Middle to Upper Cretaceous rocks of the Windy Table Complex that are thrust westward over the sedimentary rocks. The Windy Table rocks at the Dodge location are described as being intermediate to mafic volcanic rocks though regional maps indicate the Windy Table rocks east of the Dodge area to be banded rhyolites along with other felsic volcanics; Windy Table andesites, basalts and derived sediments are mapped several kilometres farther to the southeast, in faulted contact with the felsic package.

Greywacke and siltstone strike 120 degrees and dip 40 degrees northeast and is in contact with andesite and andesite breccia at the Dodge location. A northwest trending micaceous foliation is developed in the sedimentary and volcanic rocks. The andesite breccia contains coarse fragments in a dark green porphyritic matrix. Dioritic rocks occur in volcanic rocks north of the property but are not found in the Dodge showing area.

Narrow quartz veins occur in the sedimentary rocks near the contact with andesite and basaltic tuffs. These quartz veins strike northwest and are irregularly distributed. Rock sample 70005 (collected in 1985) from a 5-centimetre-wide quartz vein with minor pyrite hosted in greywacke analysed 7.5 grams per tonne silver and 0.34 grams per tonne gold (Assessment Report 14384).

The Dodge mineral claim (which contained the Dodge showing) was staked in November 1984 to cover ground along strike from mineralized quartz veins occurring on the adjacent Pud claim group. A brief program of prospecting was conducted on the Dodge claim by G. Harris and associates in 1985.

The geology of the Dodge showing is similar to that of the Pud showing to the north, where mineralized quartz veins contain auriferous arsenopyrite, galena, sphalerite and chalcopyrite. The Pud showing is located on the southeast shore of Windy Arm directly across from the old Wynton townsite.
