John Maytham we speak to Professor Roger Gibson, Professor of Structural Geology and Metamorphic Petrology in the School of Geosciences at the University of the Witwatersrand. Professor Gibson has spent decades researching the Vredefort impact structure and joins us to explain how this ancient collision transformed the landscape, why it remains one of the world's most significant geological sites, and what makes it an enduring source of scientific discovery and national heritage.

Presenter John Maytham is an actor and author-turned-talk radio veteran and seasoned journalist. His show serves a round-up of local and international news coupled with the latest in business, sport, traffic and weather. The host’s eclectic interests mean the program often surprises the audience with intriguing book reviews and inspiring interviews profiling artists. 

A daily highlight is Rapid Fire, just after 5:30pm. CapeTalk fans call in, to stump the presenter with their general knowledge questions. Another firm favourite is the humorous Thursday crossing with award-winning journalist Rebecca Davis, called “Plan B”.

John Maytham is a trained actor who made the switch to radio over 20 years ago when he joined the news team at Radio 604.

He then swapped reporting for anchoring an AM drive time show at a national talk radio station.

Once he set the bar for South African news and talk radio he accepted the challenge to join Primedia Broadcasting and help establish the newly founded CapeTalk, fulfilling the role of both News Editor and Breakfast Host.

He was the first host to switch on the mic on 14 October 1997.

Years later, he was also the first radio broadcaster to do a Google Hangout in South Africa.
