  Recent studies predict the characteristics of JWSTs deep field image using a
deterministic approach based on recent observational measurements with
corresponding ranges of uncertainty. This study presents a simplified
geometric-focused deep field simulation using an ensemble approach to
demonstrate the high variability in results due to the uncertainty ranges of
observational measurements. Two sets of ensemble simulations were conducted: a
parameter sensitivity ensemble, and a 90-member full ensemble each calculating
the percentage of the image occupied by galaxies. The estimated number of
unseen galaxies in the HUDF was found to provide the largest variability of
results. The Apparent Galaxy Wall (AGW) effect is introduced and defined as >=
50% area of a deep field image occupied by galaxies. A one-way one-sample
t-test was conducted on the 90-member ensemble, concluding the JWST is not
likely to observe the AGW effect with an estimated galaxy coverage percentage
of 47.07% +/- 31.85 but does not rule out the effect as a possibility. A
discussion is included on the potential impacts of the AGW effect being
observed and its potential to form a pseudo-cosmological horizon that may
inhibit the effectiveness of future observatories.
