Mormon recounts that "there was in Mormon a fountain of pure water, and Alma resorted thither, there being near the water a thicket of small trees, where he did hide himself in the daytime from the searches of the king" (Mosiah 18:5).
Jerry Ainsworth notes that today, a fountain of pure warm water exists somewhat north of Lake Atitlan near the city of Chimaltenango (see illustration). This spring and pond may be a candidate for the actual place of baptism of Alma's followers (see Mosiah 18:10-16). It is probable that in order to evade the "searches of the king" Alma's followers moved around in that area rather than meeting in a single location. [Jerry L. Ainsworth, The Lives and Travels of Mormon and Moroni, p. 92]
Note* From the picture and location (see illustration below), this site is probably at Los Aposentos. If so, then this site has been proposed previously as the Waters of Mormon by Clate Mask. [Alan C. Miner, Personal Notes]
